[Q] USB connection issue/Files and Folders Invisible

Hi everyone, I'm having a real problem when connecting my LTE GNexus to the computer. I wanted to copy the TitaniumBackup folder to my desktop then replace it with the one I copied over from my old Droid Incredible, but when I look at the TitaniumBackup folder on the internal storage of my Nexus, it shows as empty, containing zero files. This is impossible, as I've done a backup already and even checked with ES File Explorer that all of the backup files ARE in fact present within the folder. However, the folder appears as empty on my PC and when I copy it, only copies an empty folder.
Furthermore, I then deleted the ENTIRE TitaniumBackup folder via ES, and the computer then showed the folder was gone (so it it's not like it's not reacting to changes made). I then redid the backup, which recreated and populated a new TitaniumBackup folder, but when I plugged it back in to my PC, the new folder didn't even SHOW UP. So now I have an entire folder that for some reason is completely invisible to the PC.
I don't know if this an issue caused by the Nexus or ICS specifically, the MTP protocol it uses to connect (instead of USB mass storage), or maybe even Titanium Backup. All other folders appear to be visible and the files inside are present (to my knowledge). What in the world is going on?!
PS: Please don't just give me a workaround for the current situation like "just upload it to Dropbox". I need to know how to fix this bigger issue for future use. Though if someone could recommend to me a way to upload whole folders to the cloud somewhere (Dropbox, Gmail, anything that allows me to pull it down via a PC) that would obviously be appreciated, as every app seems to only want to upload individual files, even the new DB. THANK YOU!

Hi,
I just had the same issue with the TitaniumBackup folder not showing up in windows explorer after the first backup.
Restart of the phone helped!
Cheers

its MTP, this has been bugging me too, but for now i got a workaround (i know...)
get SDrescan, its free. it will force your phones media storage to rescan your files. once you do, you'll see your files appear in the explorer. rebooting your phone also triggers this

Thanks everyone! Man, MTP sucks...

SDRescan did not work for me. Sits there forever saying "preparing" (I did let it sit for 30 min).

So, is there any solution for that?
Missing many files/folders on MTP.

This is really ****ting me up the [email protected] wall. I've trie everything, even sdrescan does **** all. Why does this issue exist and why the **** has't it been fixed

Using wifi, I've worked around it by using some of the features in AirDroid (sets up a web server on your GNex and you can login via a web interface on your PC). File Expert can also talk to windows shares on the same wifi network, I've used this to move around some large files as well.

I'm also having this issue, I've already tried fix permissions in recovery, did a symlink (not sure if I did it correct though) and now I'm trying sdrescan.
I'm thinking of going back to cyanogenmod backing up my entire sdcard to pc flash jelly bean and put back every file...
Cause pictures I've taken with Jelly bean are showing up in the gallery and via usb, so i'm guessing copying everything back to it will do the trick.
Most annoying thing is I can flash a new rom whenever and where ever I want and be able to fix my issues, but this sdcard thing is way out of my league...

I find a solution here :

Hope it fixed the problem, I had exactly the same one

Easy workaround : in the app X-plore file manager, long-press on your TitaniumBackup folder, choose "Create Zip", then Ok (doesnt matter where you put the zip, you will cancel/delete it soon)
Voilà! My files appeared instantly in Windows as soon as X-Plore started creating the zip file. So, cancel that dialog, and enjoy your titanium backup files.

Restart phone as previously stated. Worked for me too. :good:

Reboot didn't worked for me.
I tried through ES File Explorer to copy the Titanium folder in my computer via LAN.When it started copying files, then the folder magically showed its content.Then transferred via MTP as it's a lot faster than 802.11g.
Hope someone finds it helpful.

[Q] Why do folders on /SDCARD appear empty through computer?

This is driving me crazy. I want to copy the TitaniumBackup folder from my GNEX to my Win7 PC.
Looking at the folder through Root Explorer on the GNEX all appears normal. When I look at the folder through my computer the folder is showing but the contents are backups that are almost a month older than are on the GNEX. If I delete everything in that folder FROM THE PC it still exists on the GNEX.
It is like it is looking at a different folder entirely however looking and searching through ROOT EXPLORER there are no other TITANIUM BACKUP folders.
This happens with a lot of apps. Example: I created a ZIP file using ROOT EXPLORER. The zip, viewing through ROOT EXPLORER is located in the /SDCARD/SPEEDSOFTWARE/ZIP folder however when I look at the SPEEDSOFTWARE folder via my PC the folder is empty.
I have tried both MTP and PHOTO mode. This happens with a lot of folders when trying to view them from my PC connection. Some stuff is there and a lot is not.

Hmmm, there is a /MNT/SDCARD and a /SDCARD folder (I don't know much about Linux) and the files I am NOT seeing on my PC are in /MNT/SDCARD and the files I am seeing are in /SDCARD. Why are there 2 different "SDCARD" folders? I changed the TitaniumBackup to save to /SDCARD instead of /MNT/SDCARD but the backups are still not viewable (or copyable) from my computer. I just don't get it.
So the question is, how do you "backup" the contents of the "SDCARD" directory if you can't see the files when plugged into the PC?
Well, after comparing all the "visible" files on my computer when I access the GNEX via MTP vs what I see using ROOT EXPLORER the ONLY 2 folders NOT visible from my PC are TITANIUMBACKUP and SPEEDSOFTWARE (thus is the ROOTEXPLORER app data). Why would they be hidden?

It's due to how the Android MTP service works. It hasn't scanned your internal storage for the new files/directory to present to your PC yet.
Download and run an app called SDrecan from the Market. This will force the media services on your phone to rescan the device.

[Q] Storage missing/partly hidden

Hello guys,
I have a bigger problem I hope you can help me with...
My internal storage is somehow messed up. This has effects on MTP and on some apps like the stock camera.
When accessing my internal storage by MTP from PC, only a few folders and files are visible. In contrast, if I list the content of "/mnt/sdcard" or "/storage/sdcard0" they show all my files and folders as one would expect. Also, files visible on the PC are inside this path and even when i copy a file from the PC, it is placed here.
The more serious problem is, that some apps are not able to find their files and folders inside die storage anymore. As an example, the camera app asks me to insert a sd card before taking a picture and Winamp doesn't find my music anymore.
What i tried so far:
Copying files from and to storage with Dropsync, FolderSync and ES Explorer: works without problems
I checked the rights of the files with the terminal: nothing interesting there
I cleared my whole storage (thanks to Unlock procedure) and flashed a new Custom ROM
I drank a lot of coffee because it got late
Nothing worked.
Please help, Thanks!

So thats me again.
I finally found the correct allready existing post. In this thread user dlzinc describes that one has to fix the permissions for /data/media. Good to know that i was right with permissions, bad that i didn't go through with it in the first place.

[Q] es file explorer deleted my files

So I was trying to move my files from whatever directory they were in to my storage since I had just gone from tw to miui so the directory change mess up thing happened. It would go and overwrite the new empty same name folders but nothing would show up I go back to the directory they were in and everything was gone. Restart my phone and some showed up and managed to transfer only a small portion of my pictures and some other files. My music files and some of other folders I tried transferring again and it would seem like everything went well but they wouldn't show up in my storage folder and it disappeared from the original folder it was in. They got deleted. I had about 3gb of free storage now I have 9. Sigh. So is there anything I can do to recover my files? I'm about ready to toss this phone out the window I've never had problems with es until now.

I know that there are file recovery programs for Windows and macs. You'll need to Google it because I can't remember what it's called.

I think is Recuva.

You can use data recovery tool to recover deleted files from ES file explorer. See this step by step ES file explorer deleted files recovery tutorial.
hope this helps.

Cant copy files from internal storage

Hello!
I have some files on the internal storage, from the downlad folder, that i want to copy to my sdcard, but theres no file explorer that will let me do it. I've tried both Root Browser and Root File Manager. They just give me an error saying 'Operation Failed!".
If i plug it into my PC through MTP and tries to copy the files, either to the SDcard or my own computer, windows 8 gives me an "Unspecified error" or saying "The device is off, or file not found" (or similar).
What is wrong? Why cant i move the files from the internal storage? Hope you can help me.

Sounds like an sdcard issue
Try copying files within the sdcard and within the internal storage. If it fails only when copying within the sdcard, remove it and try on a card reader on your PC.

I can without problems copy files onto or from the SDcard(from PC), but not the _internal storage_, thats the problem. The SDcard (partition?) works fine.

To clarify, do you mean the /sdcard/download folder ? I use X-plore if that helps!

To clarify, i meant the download folder on the internal storage chrome etc., saves files in that folder..
Wow that seems like a nice file manager, and it does the trick! No errors what so ever. But how come it works, but other root file managers doesnt?
And how come it doesnt work in windows? :<
Something about permissions?

I must admit that I didn't think X-plore would work either but am pleased it did; it does do pretty much everything as far as files and folders go.
I've not had a similar problem and cannot see a reason why the other methods you have tried don't work.
