Mac > sdcard file transfer, extra files - EVO 4G Q&A, Help & Troubleshooting

I noticed that when I use my phone in usb storage mode on a mac, then drag a file from the desktop to the sdcard, a second 4k file is created on the sdcard, which is the same file name but with a period in front like:
._cm_supersonic-07192010-045042.zip
I don't see this when transferring from a pc, anyone know why it does this and if I can delete these files, they make browsing the sdcard in astro messy.

The reason for the ._ (which is actually called AppleDot or DotUnderscore) is because of the File system Mac uses (HFS, HFS+)... and when transferring files from Mac to Windows or Windows file systems (Fat32, Fat, NTFS), the files tend to show up like this, it's a Unix thing which Apple has been using for quite some time.
If you want to get rid of this, you can export the following command. To make it permanent, enter this into your .bash_profile file using a text editor.
At the bottom of the file, enter:
Code:
export COPY_EXTENDED_ATTRIBUTES_DISABLE =true
More information about this:
Disable .DS_store files
AppleSingle & AppleDouble formats
Disable ._ files
Hope that helps.

Manual backup of XAPs, Favorites. Download RAR, Cab, 7z files. Full ZIP files

Hi everyone,
I'm posting a method today which i use to backup my XAP files and favorites. I hope that they will help others too and I'm posting some other tips too which i gathered around from the web and XDA. I will be constantly updating this post.
Most of the tips I've provided here are only for Fully Unlocked Phones
Backup .XAP files downloaded from Zune Marketplace
Access your phone's files using any File manager FileBrowser by ego zheng, Unique File Manager by Mohsen Unique Or TouchXplorer by julien Schapman.
Both FileBrowser and Unique file manager can open XAP files but TouchXplorer will throw an exception.
Open FileBrowser and Goto /My documents/Zune/PimentoCache/Lib/
There should be numerically named folders containing cached XAP files but with .ZMZ extension which will look like this
app0b792c7c-14dc-df11-a844.zmz Copy those files to another folder and rename the extension ZMZ to XAP. You should keep in mind that PimentoCache folder gets cleared after every few days. So you have to copy those files as soon as you've downloaded from the marketplace.
You MUST have XAPdeployer by Ultrashot installed for the following trick to work.
If you want to open ZMZ files in the FileBrowser to see which ones you are copying or renaming. Launch Registry Editor by Julien Schapman open HKEY_CLASSES_ROOT create a new key .ZMZ open .ZMZ and create a new String value "Default" enter "xapdeployerfile" in the value and tap OK. Now you can open ZMZ files in the file browser.
Backup XAP files downloaded with Bazaar App
Using Phone's file manager Or Windows Explorer on computer Goto
Application\Data\9daf0fc-a0ee-4cfc-905a-cc812d678a35\Data\IsolatedStorage
all homebrew XAPs downloaded from Bazaar will be in this folder.
Backup XAP files downloaded with wPhoManager
If you download files with wPhoManager from W.I.N.C.O marketplace all the XAPs downloaded will be in
Applications\Data\8A011F29-D5A3-4942-B865-71198AAB94AE\Data\IsolatedStorage
Screen Goes Blank during Incoming/Outgoing calls
I had this problem sometime ago when my HD7 fell real hard and started giving these problems. So I searched the web and found this solution from some website. If you are having problems (Blank screen and inaccessible phone) while incoming/outgoing calls it has to do with the proximity sensor. It goes out of alignment and that results in the black screen during the call. While the call is active, since the screen is essentially turned off by the proximity sensor, I can’t use the keypad or even hang up the call!
The fix is to press down hard on the area where the proximity sensor is. It’s located at the top of the screen – pretty much where the HTC logo is. Just press hard on that area and that should move the sensor back into place.
Backup Internet explorer's Favorites
Browse to /Windows/Favourites and copy all the content to a folder of your choice. Put them back in after you've reset your phone or installed a new firmware. You can also use IE fav Backup by Sh4d0w86 that's also a pretty good app for doing this task.
Saved Office mobile files OR copy Documents from computer to phone
All your Word, Excel, Powerpoint files you saved on your phone are stored in My documents. If you have files in your computer and you want them on your phone. Just copy all those to My documents and they will be in your files list.
Record incoming/outgoing calls complete with environmental effects
This trick does not even need any sort of unlock. Call any number on speaker and press the camera button Switch to Video Recording mode and tap Record. Your call will be recorded in a video use VirtualDub(or any other audio extraction software) to extract the audio and Audacity to reduce environmental effects if there are any.
ZIP files
By default downloaded ZIP file's content (Which can open by default in Windows Phone 7)is in Applications/Volatile/ZipView/(This folder gets deleted when you close the ZIP file, So you have to keep the ZIP file open until you've copied). but the limitation is that you have to open each file individually. But if you want to download the complete file without any content limitation. Do the following method :-
»Open your file manager on your phone OR windows explorer on PC.
»Goto \Windows\Profiles\Guest\Temporary Internet Files\
»There should be folders with names like 9FADAF33, Q110E4PZ, U0GWIYEF and U2QKY63D(exact names can differ)
»Your downloaded ZIP file will be in one of these four folders.
»Copy/Paste downloaded ZIP file to another location where you keep your files.
This method is helpful if you are downloading ZIP files which contains DLLs, EXE or any other format files which WP7 cannot open.
Download WinRar, CAB, 7Z files
Windows phone 7 does not recognize these file types so it will not download these files if you want to. With the following tip you can download these files to your phone.
»Start your phone's Registry Editor and tap HKEY_CLASSES_ROOT
»Create three new keys .Rar, .cab, .7z
»Open each key and create String "Default" with "Zipfile" as a value
»Now you can download Winrar, 7Zip, and CAB files in Internet Explorer.
If any of the above tips helps u out a little please hit thanx or reply if you have any question or suggestion.
I will add shortly:
xap handler = new registry key HKCR/.zmz and string value: Default -xapfile
unique file manager extract zipfile
Download WinRar, CAB, 7Z files
Windows phone 7 does not recognize these file types so it will not download these files if you want to. With the following tip you can download these files to your phone.
»Start your phone's Registry Editor and tap HKEY_CLASSES_ROOT

Thanks for the valuable info.
Great job
It did and did not work
The rar file can be downloaded, but wp7 cannot read it or recognize it, it shows corrupted file or unreadable file by the system.
It seems we need rar code to be native so we will be to open rar files.

i hope too but WP7 is closed like a fort, it's not developer friendly and it's really hard and time consuming to do modifications or add new features. You can put some minor things here and there but nothing too big.
Hello!
I copied and moved some .zmz file in my pc.
I renamed them in .xap and tried to deploy them into my HTC 7 Pro with Dynamics 1.21 ROM.
I tried with WPH Xap Deployer, wf Phone Tools and Phone7Deployer, but I only got errors (failed to open the manifest file. This may not be a valid xap).
I suppose this should be related to app encription...
So now, also without Reinstaller working, if we make whatever can delete the apps from the phone, we will have to pass through the marketplace, with app list opened on Zune on our pc... :crying:
Otherwise, a way could be:
1) to know an app's guid, i.e. with cache clearer
2) use a storage explorer on pc, like windows phone device manager and go to
application/Install/(application guid);
3) copy that folder into pc
4) right click on the folder to create a zip file
5) change the extension of the zip file to xap (you can do it at the end, there
some softwares for file renaming...)
A long way if you have some tenth apps installed...

You are right about apps encryption. Microsoft recently encrypted all their XAPs on marketplace.

Nonetheless, if we've got encrypted XAPs specific to our devices, we ought to be able to install them on the device somehow from within the device. We'd just need to initiate the install routine. Does anyone know how to do this?

Did you try to look into the Angry Birds folders in your device if it saves something,
for example using FileBrowser (http://forum.xda-developers.com/showthread.php?t=1544399) or Webserver from GoodDayToDie?
If there's something there, you should be able to copy your states in your pc and put them back in your device, I think...

[GUIDE] How-to copy files from/to your device

Problems
"The contents of the /sdcard partition is not properly displayed by Windows Explorer. I'm missing files/folders and/or I'm seeing files/folders that shouldn't be on my /sdcard. When I browse my /sdcard with a file manager app the contents are displayed OK."
"Whey copying files, the process hangs during transfer. Happens mostly when copying a large number of files."
"The /sdcard contents are listed, but it's not possible to copy anything from or to the /sdcard."
Cause
The Galaxy Nexus does not support the USB mass storage protocol, but relies on MTP (Media Transfer Protocol) when connected to a computer using a USB cable. The implementation of MTP is buggy at best. Transferring files is slower and less reliable when compared to USB mass storage. Windows Explorer is often unresponsive for shorter or longer periods when browsing the /sdcard with it and may not list the contents of the /sdcard properly. These problems are Windows version independent, despite the fact MTP is natively supported since Windows Vista. Problems are reported with XP, Vista and 7 on x86 and x64 architectures. Using alternative file managers instead of Windows Explorer also doesn't resolve the issue.
Solution
I've find it best to work around this issue by avoiding to use MTP by using the following methods:
Direct methods
1) Using ADB
Prerequisites
- ADB binaries
- USB debugging option enabled in developer options
- Galaxy Nexus connected to the computer with USB cable (rooted phones can also use ADB via a Wifi connection)
Steps
The Android Debug Bridge allows to copy files/folders from and to the /sdcard by using the adb pull and adb push commands on a Windows command line interface (DOS prompt). You'll need the ADB binaries on your computer to use this method. You can get them by either installing the Android SDK or by downloading this small package with all the binaries you need (recommended): http://forum.xda-developers.com/attachment.php?attachmentid=1031911&d=1335747189
Extract the files to a folder of your liking. To use adb commands, you must open a command line and either navigate to the folder that contains the adb files (cd D:\MyAdbFilesAreHere) OR you can add the absolute folder location of that folder to the Windows PATH system variable so you can use adb commands regardless of the current directory you're in.
Syntax
adb push <local> <remote> - copy file/dir to device
adb pull <remote> [<local>] - copy file/dir from device
Examples
If you want to copy your entire /sdcard to D:\MyGalaxyNexus: adb pull /sdcard D:\MyGalaxyNexus
If you want to copy just the DCIM folder (camera images): adb pull /sdcard/DCIM D:\MyGalaxyNexus\CameraImages
If you want to copy a file from your computer to the /sdcard: adb push D:\MyGalaxyNexus\musictrack.mp3 /sdcard/music
Advantages of this method
- Good transfer speeds.
- Possible to automate backups by creating simple Windows batch files.
Disadvantages of this method
- Using a CLI is less intuitive than a GUI.
- File attributes are not preserved (created, modified, accessed attributes).
2) Accessing a shared folder on your computer with a file manager app on your device via Wifi
Prerequisites
- Wifi connection
- Computer and Galaxy Nexus connected to the same LAN
- A shared folder on your computer
- A file manager app that supports accessing LAN shares (for instance: ES File Explorer)
Steps
Create a folder anywhere on your computer and share it by giving the user "Everyone" read/write permissions on it (note: if you are on a network, this means every user on that network can access your folder AND write/delete files in it. For most home situations that's not an issue though): right click on the folder > Share With > Specific People > use the combox to select "Everyone" > click Add. Now change the permission level to Read/Write. You also need to turn off 'password protected sharing' for this to work via Control Panel > Network and Sharing Center > Advanced Sharing Settings > expand Home or Work > section Password protected sharing > turn off password protected sharing.
Finally, install ES File Explorer via the Play Store and launch it. Change the view to LAN. Tap New > tap Scan. Your computer's IP should be listed. Tap it. It will show an overview of shared folders. Ignore the admin shares Windows creates by default (all shares with a dollar sign suffix) and tap the folder you created earlier. Now you can copy any file from/to this folder using ES File Explorer.
Advantages of this method
- Decent transfer speeds.
- Copying files/folders with a GUI.
Disadvantages of this method
- All copy operations must be done on the phone.
- File attributes are not preserved (created, modified, accessed attributes).
3) Using an FTP server on your device
Prerequisites
- Wifi connection
- App that allows FTP access to your device (for instance: ES File Explorer)
- FTP client (for example: FileZilla)
Steps
This is pretty straightforward: open ES File Explorer, go to 'settings' > 'remote settings' and enable 'remote manage'. The app will provide you with an IP address & port which you have to enter in your FTP client. After you have connected, you can transfer files from/to the device.
Advantages of this method
- Decent transfer speeds.
- Copying files/folders using a Windows program.
Disadvantages of this method
- File attributes are not preserved (created, modified, accessed attributes).
Indirect methods
1) Using the cloud
Prerequisites
- An account with a cloud storage service such as Google Drive, Dropbox, Box.com, etc.
- A Wifi connection (not an actual prerequisite, but using mobile data is a lot slower and will have a large impact on your data plan)
Steps
This is pretty straightforward to explain: upload the files you wish to backup to the cloud service of choice, and in turn download them to your computer.
Advantages of this method
- Decent transfer speeds.
- Copying files/folders with a GUI.
- Preserves file attributes.
Disadvantages of this method
- Not a direct method.
- Dependent of third-party services (service or internet connection might be down).
2) USB on the go
Prerequisites
- USB on the go cable
- USB thumb drive
- Root access
- App "Stick Mount" by ChainFire
Steps
With stick mount, a USB OTG cable and a USB thumb drive you can mount a USB thumb drive on your phone. This allows you to copy files and folders from the /sdcard to the mounted USB thumb drive using a file manager app. In turn, the files on the USB thumb drive can be copied to your computer.
Advantages of this method
- Good transfer speeds.
- Copying files/folders with a GUI.
- Preserves file attributes.
Disadvantages of this method
- Not a direct method.
- Needs a rooted device.
- Dependent of a third-party app (might be pulled from the play store or will not be updated).
GPsoft Directory Opus
Directory Opus is a file manager for windows, offering complete system integration thus a full replacement for Windows Explorer. Since version 10.5, Directory Opus has full MTP support built-in. Although certain operations cause long delays (copy-paste for example), the MTP support is robust enough for me to abandon ADB for file transfers.
This is great. Well done. I will certainly link to it in the 101 thread. If you want, I can also add the text to the actual thread (with credit of course) - your call.

thanks for putting this together man.

AirDroid
For people who really want to use Windows Explorer effectively, there is a very good app called Samba Filesharing. It runs a samba server on your Android device, which you can then set up as a network drive in Windows. Unlike MTP, all Windows Explorer functions work, eg right-click context menu and filetype associations. It works via WiFi hotspot or normal WiFi connection.
The disadvantage is that transfer rate is limited to about 1.8 MB/s. But for simply browsing files, doing housecleaning, and less-than-huge file transfers, it provides all the familiarity of Explorer. I don't know if it works with wired USB tethering, but if it does, that would also give much faster transfer rate.
thanks for the comparisons in a simple list :good:
FYI, for linux users:
When using adb, no need to download any drivers, just use adb [to get adb, just download platform-tools-v19.zip or if there's a newer one when you read this...].
If you're using adb and try to move files remember to also put the / at the end of the filepath for your android device.
i.e.
./adb push nameofile.zip /sdcard/
Also, before attempting to manually mount your gnex, it already may be automatically connected.
After connecting the usb cable - verify by ./adb devices

Hi.
Thank you for this guide.
I'm getting crazy for a problem: I would like to restore the photos without change the creation date.
I tried everything to copy file, ftp server, shared folder, ADB but the date changes: I have to give up or is there a method to preserve it?

Thanks, some extra things to note. The ES Explorer FTP server (or perhaps any FTP server) on the Galaxy Nexus is prone to disconnection and may hang if you try to copy the whole folder with a client app like WinSCP.
For WinSCP I found that when doing transfers to enable "Transfer files individually" helps with the reliability.

MTP and hidden files

Hello,
THere is a strange thing with the mtp mode, when i connect my phone. Ican explore it go to the directories. No problem. BUT, i don't see the hidden files or hidden directories in the explorer. The file are or directories begin with a .. I see it in the note ii with asto os es file explorer, but when i caonnect i can't see them.

Yes why not, but if i understand in mtp mode no hidden files, in the windows explorer. What a shame, really i dislike MTP protocol, the usb mass storage was more easy

[Q] thumbdata3 file 1.5 gb Need Help

Hay guys
I am facing some strange issues on my galaxy nexus 4.2.2 unrooted
I have notice that in my phone there is a file name THUMBDATA3-1763508120 in DCIM--->thumbnail folder of size 1.5 GB.
And even after deleting this file no space of my sdcard is released . Means my SDCARD is still showing the same space as before .
and after some time it recreate again with same size when i use camera for some time.
One more thing in my phone I have 9.35 GB of data content but SDCARD is showing 11.5 GB of space out of 13.3 GB
This may help , please confirm
Using a disk space analyzer, I was surprised to see that my Android tablet had 1.03GB of photos. This was odd to me, because I knew there were only a couple of photos on the device.
I pinpointed the problem to thumbnails. These are tiny copies of photos used by some apps to more quickly display pictures. Specifically, the 1GB was being taken up by a thumbnail index file, and I didn't need to lose that 1GB to a function I don't use on the tablet. I erased the file as follows:
1. Open a file manager on Android. I use File Manager from Rhythm Software.
2. Ensure that it can display system or hidden files. This is an option somewhere under Settings. In File Manager, tap Menu > Settings > Show Hidden Files.
3. Navigate to \mnt\sdcard\DCIM\ .thumbnails. By the way, DCIM is the standard name for the folder that holds photographs, and is the standard for pretty much any device, whether smartphone or camera; it is short for "digital camera IMages." Another BTW: when a folder name is prefixed with a period, then it is a hidden folder in Android (such as .thumbnails).
4. Select and erase the file that's about 1GB and contains the word 'thumbdata." The exact file name will vary.
After I did this, image viewing apps like Gallery operated just fine, with no apparent slowdown from the loss of this file.
In this way I freed up 1GB on my Android v4 tablet, 1GB on my Android v4 phone, and 750MB on an older Android v2 phone.
Keeping the 1GB Free
Because .thumbdata is a system file, Android recreates it. Indeed, you may find more than one copy in the .thumbnails folder, if you have reinstalled Android or similarly redid the system in some way.
To keep Android from creating the 1GB file anew, we need to create a dummy file that fools Android. In short, we create a text file with a text editor, and then move it to the thumbnails folder. Here are the steps to doing this:
1. Use File Manager to determine the exact name of the thumbnail index file. On one of my Android devices, the name is .thumbdata3--1967290299. Write it down.
2. Start a text editor or word processor on the Android, and then create a new text file.
3. Use the Save As command to save the file in the DCIM folder. (We move it to the .thumbnails folder in a later step.) Save it with the same name at that index file, such as ".thumbdata3--1967290299". Now, depending on the text editor's capabilities, it might not allow the "." prefix or a blank extension. Thus, you might end up with thumbdata3--1967290299.txt as the file name. We fix this in a later step.
4. Exit the text editor, and then switch to File Manager. Now, it is important you use a file manager like Rhythm Software's File Manager app, because it does what some others cannot: it can (a) rename file extensions and (b) access hidden folders.
5. In File Manager, navigate to the \DCIM\ .thumbnails folder. If the thumbdata3 file is there again, erase it again.
6. Move up a level to the \DCIM folder, and then right-click the thumbdata3--1967290299.txt file name. ("Right click" means hold your finger down on the name until a menu appears.)
7. From the menu, choose Rename, and then rename thumbdata3--1967290299.txt to .thumbdata3--1967290299 -- (a) add the dot (.) to the start of the file name, and (b) erase the ".txt" from the end of the file name.
8. Click OK (or Rename) to finish renaming.
9. Right click the file name, and then choose Move (or Cut).
10. Navigate down to the .thumbnails folder, and then tap Paste.
The dummy file will now prevent Android from creating the huge index file.

Hay guys
I am facing some strange issues on my galaxy nexus 4.2.2 unrooted
I have notice that in my phone there is a file name THUMBDATA3-1763508120 in DCIM--->thumbnail folder of size 1.5 GB.
And even after deleting this file no space of my sdcard is released . Means my SDCARD is still showing the same space as before .
and after some time it recreate again with same size when i use camera for some time.
One more thing in my phone I have 9.35 GB of data content but SDCARD is showing 11.5 GB of space out of 13.3 GB
Click to expand...
Click to collapse
I just answered this in another post but check it
I have root on my device, so I did the following.
Using Root explorer I went to the folder /DCIM/.thumbnails (hidden) and deleted the huge file. Then with the "+" I chose "New file" and named it the same as the previous .thumbdata3-.... it created a file that is 0 Bytes and then I went and used the camera and the apps, so far the file stays the same size, so maybe that trick will work for others too. Good luck.

How to transfer files from Phone to PC with Dex?

Ok so in the description of dex website it talks about easily dragging and drooping files between the pc and phone. But i can only seem to drag files from PC to phone and not the other way around. How do you transfer files from the phone to the PC?
I have the same question ...
windows shared folder using es explorer or total commander with plugin

Yeah I'm also curious as to how to get this to work on my MacBook.
[Pasting text from Samsung DeX to a PC]
1. Using a mouse, click and hold then drag to select the text that you'd like to copy from the Samsung DeX screen on a PC. Then, press the keyboard shortcut for copy or right-click the text and select Copy.
2. Place the mouse cursor in the area on the PC where you want to paste the copied text. Then, press the keyboard shortcut for paste or right-click the area and select Paste.
[Transferring files saved on your smartphone to a PC]
1. Open the My Files or Gallery app on the Samsung DeX screen of your PC, then select the files that you want to transfer.
Click and hold files with your mouse to select them. Then, click and hold them one more time and you will be able to drag the files to a different directory. (If you update the My Files or Gallery app to the latest version, you can select and move files just like you would on a PC.)
2. Drop the selected files on the desktop of your PC or its File Explorer.
※ If you drag and drop an image on a Microsoft Office document, you can insert the image into that document.

You can copy from most Dex folders i tried from Dex to PC . Open files tick file or folder then click and hold down on the same file or folder until it shows as floating from the original position then drag it out of the DEX Window and place it in your PC folder Done.
Neither of the solutions above worked for me. I thought the bottom solution was working but it only put a temp file in my Pc. then when i tried again it said the file already existed. I cancelled out and now my pictures are gone.
Use a usb cable and transfer directly.
Keep it simple.
Always copy, then verify, then delete; not cut and paste if files are important.
Best to use a SD microcard as a data drive in the 10+ as well as backing up those files on a PC.
If not in the trash bin those files are most likely lost.
Easiest way I found is open PC and phone in Dex...then open file explorer on PC... In file explorer you should find your phone...should be under This PC /phone mine says This PC / S20 when I open the S20 it is just like using explorer on any drive. I cut and paste the files I need from there.
Okay after being totally frustrated, IT DOES WORK!!! You can't copy files to all locations on you windows PC like network drives but it definitely works dragging to desktop and root level hard drives, I did C: and E:, both direct attached to PC. I also did USB connected external hard drives at the root level.
Also, aholic_2, you've ALWAYS been able to transfer files the way you mentioned, for 10 years or more, you don't need DeX to do that either.
Cheers
