[Q] All files not showing on PC

I have tried with file manager and found the files i was looking for in android/data/something but when i connect my GN to my PC (win7 32bit) i only get a few folders and files,
I have tested with both USB modes and I only get the basic folders such as
Alarms, Android, DCIM, Downloads, Movies, Music, Notifications, Pictures, Podcasts, Ringtones.
and the file manager reports more folders present :/
also the files i'm trying to access are within the android folder (which is visible on PC) but in filemanager there are 10-20 folders found in android/data that are missing on PC. PC only shows 3 folders in android/data
It also appears to be possible for other users to access the exact same file at the exact same filepath, why can't I?
is there a feature on GN or ICS that makes it impossible to access some files from the PC or is this a bug/flaw?
in case you guys need to know what files i'm trying to access, it's the game files to GTAIII

I kind of have a similar problem.
When i connect my phone to a windows 7 computer it mounts okey and shows me the files. If I create a folder on the phone from windows explorer, unmounts the device, I can not see this folder on the phone via a file manager unless i reboot my phone. This also applies the other way around. If I create a folder on the phone from a file manager, then mount the phone to the computer, I can not see the folder until I reboot my phone.
Is there a fix for this? Is it a bug? How can i resolve this? It's very frustrating.

MTP/PTP doesn't offer all the features the full USB transfer mode has. Search will help you find the pros and cons of this.
Workaround: Use an app like WiFi File Explorer or Airdroid.

Folders Not Showing Up Correctly

So, some of my folders are not showing up as folders when viewed on win8 (windoze explorer) or on the mac through the Android File Transfer (ATF) app when I connect the tablet. It's hard to describe, but it's as if they appear as some sort of unrecognizable app or file (not a folder) when viewed on the computer through windoze explorer or AFT. The Strange part is, it's inconsistent. If I create folder using root explorer, it shows up as a folder on the tablet, but that folder is not viewable on the pc or mac. Same thing if I create the folder on the tablet using windoze explorer or the ATF on the mac. When I reconnect the tablet, the folders are not viewable as folders. Everything seems to work fine though; fastboot, adb, etc. The tablet is recognize on both platforms when connected and the appropriate viewer opens, but some of the newly created folders don't appear as folders. Anyone else experience this or know of a solution?
edit: nvm, I figured it out...

Can't see files in certain directories (including DCIM) over file transfer (MTP)

Hello, today I plugged my phone in to try and transfer some photos I'd taken earlier, and to my surprise could not see the photos in the DCIM folder. Using FX File Explorer I can explore that folder just fine on the device itself, and see everything.
This problem seems to be affecting several folders, but not all of them. Sometimes it affects different files in the same folder differently. For example, I have some .pdf and .apk files in my Download folder, which I can see on my phone, but on my PC I can only see some other files in that folder, including a .zip file. The issue appears to be based on the date the file was created, as outlined in this post in Google Support forums. I had no success with the cache-clearing of External and Media storage system apps outlined in that thread. I had success with being able to view all my /Downloads/ folder items by putting them in a subfolder and then bringing them out again into Downloads. The trick did not work with the DCIM folder for some reason.
I am rooted, but this issue has persisted through at least one re-flash of a stock image (I just updated to the newest July build without wiping all my data).
The only thing I can think of is that I ran this command to change the permissions of /su/bin when I was trying to get Android Pay working and perhaps that screwed something up? But wouldn't that be reset after the stock image was flashed anyway? Or would I need to wipe to do that? And even so, it still doesn't explain why it only affects certain files and folders.
Thoughts on things to try? Is there any way to undo that chmod command? FX File explorer says my current permissions on that folder is 0755, could that even be causing the issue? Apparently the change to 751 failed.
The issue persists using different USB cables and ports on my PC.

Did you have any luck figuring this out. I am having a similar problem as well.
I have always been able to transfer music from my computer to my nexus5X's Music folder with no problem. Today, something isnt working right. When I plug the 5X into my computer and select File Transfers, I can see all my files on the 5X. When I select the Music folder, it opens but only shows 237 songs. When i look at the folder on the 5X is shows 1016 songs. For some reason when connected to the computer it cant see all the files in the music folder. Also, when I try to copy a file to the music folder windows give me an error and says "The device has stopped responding or has been disconnected" If i try to copy is somewhere else on the 5X it works. I just can send it to the music folder. What can I do to fix this?

I actually noticed this before the update to 7.0. I used TiBU but the folder was not there. Using root explorer I can see the folder. I placed the Titanium Backup folder into another folder and then I could see it via the PC.
I uses a usb 3.0 port on the PC , have not tested 2.0 atm.

This is a typical MTP bug, just find & clear 'Media Storage' system app data, reboot. Dont connect PC before media scanner service finished.
You will lose media playlist, though.

cant copy files, although they are shown// on usb plug,file transfer can be selected!

Moto G5 XT1676
LineageOS 15.1 / Magisk 16.0
PC: win7 x64 pro
i connect my phone per usb to pc and select transfer files
in the explorer moto g5 i can select and i can navigate through all my folders(internal and sd card)
e.g. titanium backup folder on the internal storage i want to copy the backup files to my win 7 pc
i select 470 files press copy and select a folder on my win7 and paste... but no files would be transfered.. no message pops up, and nothing is transfered
i tried same with pictures to trasfer them.. can select them(they are all in the folder on internal storage) copy them and want to paste them in a folder but paste process just wont start without error message
same happens when i try to copy files from th external sd card....
problems seems to hunt me down on every step i do ~_~

If doing a media rescan doesn't help I suggest you take a logcat whilst trying to copy files and give it to the rom developer
Use this app to media rescan - you may get several force closes whilst doing it - just click reopen app or something like that - also make sure there is no USB connected whilst you scan

As a work around you can try enabling adb debugging & then using adb to pull the folders
Or
Boot to recovery & try copying the files whilst in recovery (my official twrp fully supports MTP but I don't know about the 64bit version)

in short, fixed the transfer problem by installing "MyPhoneExplorer"

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
