unable to detect files with file manager - Nexus 7 Q&A, Help & Troubleshooting

On my Nexus 7 running Android 6.0.1 build number MOB30X, I cannot detect files or folders using a my File manager or when connected to my Win 10 PC. Another Nexus 7 usng the sames lead connects to PC perfectly and File manager works fine. the problem arose when my grandson broke screen on his Fire tablet and I wanted to transfer his Minecraft files to another tablet. I managed to get the files off his old device and uploaded to Dropbox The Tablet I wanted to transfer to works perfectly on all the games etc. but I cannot get to the relevant folder. I have got hold of another older Nexus and was able to transfer the files. why wont the other one allow access to the folders?

[Q] File transfer workaround

I'm wondering what others file transfer workaround is.
For larger movie files (1-2GB), I have been uploading one by one to Dropbox, then downloading onto my tab. But this is awfully time consuming.
Anyone have a better workaround until File Transfer recognizes the 10.1?
I'm really confused by all these threads about file transfer not working
I have had no problems whatsoever
is it because you are using a mac?
i have file transfer problems, too. trying to transfer a huge file / large number of files via usb and windows file explorer just aborts the transfer after a few minutes without any error message.
currently im using "wifi explorer" fpr transmitting files to my tablet. it's a cool app i've already been using on my android phone, too. with this tool you can access your tablet/phone with a browser (web-interface), once you've started wifi explorer and you're connected to your wifi.
It's not so much so a specifically Mac issue or Windows machine issue, apparently quite a few of the IO tabs just simply cannot or won't be recognized by either OS. I know of this first hand cuz neither my Mac nor Windows 7 ultimate machines see my tab.
Uplinked through my mind
I found out that the computer won't pick up your device if USB Debugging mode is on. After I disabled that and had the KIES drivers installed, Windows picked up the device without any problems.

Trying to copy several, small files from my SD card

Hi,
I’m running into an odd problem.
I have a Google Nexus 7 Tablet. I’ve unlocked and rooted it with the Toolkit. I’m attaching it via USB on a Windows 7, 64 bit system. I’ve installed the PDANet drivers.
I’ve made a back up of my tablet using Titanium Backup. Within the Titanium Backup directory are many small files, that I’d like to copy back onto my desktop for safe keeping.
However every time I copy the directory over to my PC using Windows Explorer, only a fraction of files get copied, I’d say about 20%. I’ve tried it several times, but, can’t seem to get it to do a complete copy. I’ve tried selecting the entire directory and the all the files (select all) without success.
When you plug in the micro USB cable to your tablet, does it automatically go into mass storage mode (though I have selected Mass Storage mode as my option).
I’m coming from several Samsung devices and I know there are a few ways to enable mass storage mode on them, and at a minimum, you have to choose to mount the SD card. Is there something similar with Asus devices?
What am I missing?
Thanks!
I rarely send files via the USB port... normally just use the wifi connection. Just sent all the TI backup files via AndFTP to a server over WiFi and it only a little more than 5 minutes.
I then for the first time, hooked up the N7 to my USB to transfer the files to my notebook.
Didn't make any changes.
Created a new directory on my Notebook (Win7Pro) and then opened the drive on the N7, found the TitaniumBackup directory and selected all the file (not the directory holding them).
Took about 5 mins to move the files which was about the same as the Wifi transfer.
Not errors, and all the files got there.
Not sure if that helps you...
Oh. the N7 is rooted with TWRP recovery on it but otherwise Stock.
BTW.. this morning I tried this app which is a sync app between my workstation at home and the Droid. Worked good enough I upgraded and now have a number of manual syncs setup (droid to computer)

Hi krelvinaz,
Thanks for taking the time to test that for me. I did exactly the same procedure as you. I'll play with it some more and see if it was just a bad driver install or something. Perhaps I'll try it on my laptop at work...
And thanks very much for the link... that app does look promising indeed. I really appreciate that it doesn't sync with the cloud, but with my pc. That's great.
Thanks again for your help!
Update:
Ok, well I tried to copy the same files on my work laptop, which is running XP, and without any additional drivers, and it stopped at exactly the same place, at one particular file.
I then deleted that one backup file, and tried to copy the directly again, and it worked. I then tried again on my Windows 7, 64 bit desktop and it too was successful!
I guess that file was corrupted or something.
I'm glad I figured it out, and thanks again krelvinaz.
I got my N7 today. Just plugged in USB to my computer and copied my "backup-apps" folder and my MP3 folder from my phone. Moved very fast, now I have about 150 .apk's I can install if I have recognition problems with the Play store, and 2000 songs.... using up my "16" gb fast... about time to root and add stickmount.

Nexus 7 File copying errors

Hello,
I've recently purchased my Nexus 7 and it's a great device, except for an infuriating problem.
Yesterday, I was able to copy files straight to the tablet from Windows. Today, every file hangs at 'calculating' and then proceeds to crash windows explorer and require me to pull out the usb cable.
I have tried usb debugging on/off, renaming the files to give different extensions and still nothing copies over. Only tiny files manage to, at around 600kb each.
TL;DR: I was able to copy multiple file types to my Nexus 7, now I can't copy anything bigger than a tiny photo.
Thanks!
Isn't MTP "great"? Wish Google will get it and bring back to USB Mass Storage.
We all remember how bad file-copying by ActiveSync was and that's why UMS took off as a much more robust solution.
Do you know how to fix the problem though? I can RAR my files and then copy them, but that is impractical.

I've tried using bulk file copy programs, but it says the destination is invalid.
I wonder if that is because the PC reads the Nexus as a media player, and not mass storage.
Has anyone fixed it yet?
Same problem here. WiFi Explorer works to copy the files. Not as fast but worked for me. I use the Pro Version, here's a link:
https://play.google.com/store/apps/...mNvbS5kb29ibG91LldpRmlGaWxlRXhwbG9yZXJQUk8iXQ..
Have you tried simply renaming the file extension to something different until you get the file transfered over?
I'm stuck at work or I would take a look at it myself.

Have to agree with you, MTP is hopeless. I've tried to copy a Titanium Backup folder numerous times and it never does a complete copy. How pathetic is this!
I've had to resort to using SMB with Ghost Commander and that is very slow! There must be a better way! Help!
mtp is horrific...

Same here. It copies about 70% of the files from the Titanium Backup folder in Nexus7... and then stops (as if completed). But when I check the destination folder on my PC, 30% aren`t transferred. How can we have such pathetic file transfer, in `this` day and age?

Currently copying the files to a separate folder on my computer then cutting those files onto my nexus
7 works for me but is bothersome most of the time.
I just copied a 350Mb folder of files to the N7. It took 30 seconds. Then I copied it back to my desktop and it took 21 seconds. I'm stock, rooted, 4.21, usb debugging on with MTP, using the original usb3 cable plugged into a rear usb port. There must be something else going on with your devices.
I also noticed that problem. But discovered that it only show up when you start "Play music". If you have started the app and would copy something just reboot . works for me!
Nexus 7 32G, European stock rom
I have the same problems as stated before. But i also noted this: when i add a new folder anywhere on the devices memory with Astro, for example a folder with pictures and shortly after i want to copy that folder to my PC. The created folder is missing and nowhere to be found while browsing the device via usb in windows explorer. Even after rebooting the pc and nexus7. Its like the index of files doesn't get refreshed often. When i tried again a few days later, the folder appeared in explorer just fine.

Only time I have seen this problem was when I tried to copy files directly to the root of the storage directory. Try copying to an existing folder on your nexus and see if it still fails.

I shut off my Bluetooth and the problem went away.
Had greater luck with this renaming or, zipping the files. It seems if the file extension isn't recognized as being handled that it will be denied after it finishes copying.

I had the same problem two days ago ... ijust ignored it and the next day everything was working fine ... i guess try restart PC and Tab both
Try this
If you have wifi, try Airdroid! Worked for me! & when the cheapo charging port gets loose, get a "Qi" charging station. Lay your device on it and it charges right through the case, wirelessly.

[Q] Problem with file transfer (connecting to PC)

I've bought a Nexus 7 (32GB) from BestBuy a few days ago. Works perfectly, but I don't like the file transfer method. I've been using the old Archos 32 a long time before, and I've helped a lot of friends with their own Andorid phones. We used to mount and unmount the devices to transfer files to computers. Mounting meant I was not able to use it, but I could transfer files. Now on my Nexus 7, I can do both. At first sight, I was quite happy about that, but I've realized it used similar file transfer methods as my very old 2005 mp3 player. Everytime I dump songs into my tablet, it tells me the file is not supported. I don't care about that, but it didn't used to be as ****ty as that with other Android phones. Quite a disappointment.
Now I started downloading stuff with tTorrent, and files are even more fricked up. I've set my download location as /Download/Torrents, as I used to do before. Back on my PC, I wanted to copy the torrented files, but they weren't there at all. Even at default location. With ASTRO ans ES file managers, I can clearly see they are at the right place. But the PC connection doesn't cooperate. I made a little search, and found out they were all hidden in a /storage/emulated directory on my PC. But only half my downloaded files were there (yeah, about 4GB hidden somewhere).
Now I'm kinda stuck in a trap. Where are my files? Would there be any way to return to the "normal" mount/unmount transfer system? I tried the MTP and PTP thing but both are weird and hide my downloaded files. I can't transfer files my files again via WiFi as we don't have much bandwidth up here in Canada. Computer doesn't support Bluetooth (and neither NFC lol). I just want the old file system back. Anyone has already faced the same situation or could help? Thanks in advance.
