This article is about the galaxy nexus but explains very intelligently how MTP storage works and why google chose to use it. Thought you guys might find it interesting too.

Interesting. But what I would really like explained once and for all is why MTP still limits us to 4GB files, when the file system on the Galaxy Tab 10.1 is not limited. I routinely encode 720p movies at high bit rate and put 5 and 6GB files onto my tab via Wifi and FTP with no problem. Yet, Kies file transfer won't allow this. And when I uninstall Kies, and use what is supposedly the built in windows 7 MTP protocol, I still max out at 4GB.
Does windows 7 MTP also limit file size to a max of 4GB? Is there ANY way to use MTP to transfer large files. I've heard ADB push works but is very slow - I am amazed that there is still no way to transfer larg files to this thing other than Wifi/FTP.

I can transfer regular documents and music, but anytime I try to transfer a video my computer will completely freeze. I'm not sure if it's videos or any large file but I'm not sure what to do here. Anybody have this issue?
Try using/getting a better computer?
More I information about "computer" would help. What OS, how much memory, what proc, size of the file, hard drive size etc. otherwise it sounds like someone saying "yeah my car is making this noise" not very specific you know?
-win7-64
-2ghz intel core 2 duo
-4GB ram
-tried files ranging from 200mb to 700mb
Have no problem transferring the same file to galaxy S. Using Kies it doesnt give me the option to "add file to device" or anything.
The tab still shows up as portable device GT-P7510. Cannot get it as a mass storage device.
If the Movies is too big to transfer just use (HJsplit 3.0) and split the movie in half and then transfer it over to the tab, use wifi explorer pro to transfer it works flawless
they are never too big with adb push

Is that so? Even when pushing to /sdcard?

Unlike phone-derived Android, /sdcard on our devices isn't really an SD card. It's actually the exact same partition as /data.
It's just symlinked so that apps which expect /sdcard don't break.
As it's an ext4 partition, it doesn't have the 4GB file size limit of FAT.
This, by the way, is why our tabs don't support USB Mass Storage but instead implement MTP. USB Mass Storage exports the raw block device, MTP operates on files. This allows it to be used when other apps are also using /sdcard, and allows the ext4-ness of /sdcard to get hidden. The disadvantage is that it's far less standardized than USB Mass Storage. MTP seems flaky on our devices, but ADB (Android USB debugging) is nice and solid.

Once you have the movie on your Tab (in a million or so pieces) how do you play it? I have done what you said but I can't get it to play in order -- just plays one file and quits...Please help
just transcode it with handbrake or dvd catalyst - problem solved! entire movie at manageable file size with excellent quality

Just chose the next file i haven't managed to get them to play in order, working on it.
MKV solves ALL of these problems.
Download mkvtoolnix for your OS
This toolset allows you to do the following very easily:
Add any video/audio source to MKV container without compression
Split MKV into any size chunks
MKV split into chunks can be "linked" and if the player fully supports it, it will automagically find the next chunk to be played. I dont think diceplayer supports the link functionality of mkv. Boo hoo you need to pick the other chunk to play when one runs out. Not a deal breaker.

Thanks -- I originally didn't see that you could set the files to a 3GB file and I was just using the default of 1048k.....Now it is only in 3 files instead of a million!!
Yeah...I tried to transfer my MKV files to my nexus 7 which is 100% stock and every time I drag and drop the MKV files over (Doesn't matter if I drag and drop 1 or 50) Windows explorer crashes. Anyone found a way to fix it from doing this...?
Is it over 4gb? I believe it's formatted as FAT32 and 4gb is the max file transfer.

No...they are all under 100 megabytes.
I should also note that I have to use MTP..because UMS isn't supported. But even if I try to sync them via windows media player it fails all the time.
Have you transferred other file types? This is most likely a stupid suggestion but maybe try renaming them first? Maybe it's something with the mkv extension or an illegal character in the file names. As I said, dumb suggestion, but once in a while those are the ones that work.
technically, it shouldn't be a problem. Did you checked whether JB supports MKV files? Or did you tried to transfer another type of file this big?
Try to upload a single MKV to Google Drive and download it to N7 and then play. If it works, then transferring should not be a problem.

I have it hosted on my local apache web server and I just browse to the webpage and tap on it and it loads right up and plays in MX player...However no matter what I do I CANNOT transfer the files to the nexus 7...
I just tried it out, copying a 720P MKV file from Windows 7 to the Nexus 7 over MTP. Worked fine for me.
Well no matter what I did it wouldn't work...I ended up putting the files in a .tar file and copying them over and extracting the archive...it worked then but its a HUGE pain in the ass.

Found a workaround:
Change Usb settings to PTP
1. Menu>Settings>Storage>Menu>USB Computer Settings
2. Tick Camera(PTP)
3. Transfer to Pictures folder
4. Using a file explorer of your choice on the device, transfer to final destination folder
5. ????
6. PROFIT!!!1!
I've successfully streamed mkv files to my N7 with Dropbox and using a local server and ES File Explorer. Haven't yet needed to transfer onto the limited flash of the N7 but I am sure that will happen for my next business trip so I will try it tonight to see if I have any issues with large files and smaller files.
I can't get mine to transfer. Even tried the picture folder trick. Of course I have the .wmv digital copies of movies I'd like to transfer. Going to try and convert them to mkv at least.
Aside from dropbox, would google drive work as well for streaming?
Very odd. I get a prompt saying my device might not be able to play the file but do I want to copy anyway. I just click the "do this for all" and say yes. You on Win 7?

I have both the Galaxy Nexus and Nexus 7 and have the same problem from my Windows 7 Home machine, but at work my Windows 7 Premium machine copies MKV files without a problem - on my home machine it crashes Windows Explorer every time...
There are several ways I've found to copy the files without converting them to MP4/AVI files first:
Dropbox, Google Drive, AirDroid - all of them treat the file as a "captured video", but at least AirDroid doesn't NEED Internet access, while the other 2 do
I'm not sure if it's a driver problem within Windows, but if I find any further methods I'll post here...

Do your PC has Dixv Plus codec installed? If so, uninstall it will fix the problem.
There is another thing that cause window explore crash, some of the mkv files don't have header compression removed when muxing.
Using Windows 7 Home Premium x64 on a laptop, no problems copying MKV files to a rooted Nexus 7 16GB running JB via USB. Even used ES File Explorer to copy, wirelessly, an MKV video file from the laptop to the Nexus 7. The video file (created with Handbrake from a ripped DVD) was 1.05GB. Screen captures of both the copying from Windows 7 and the file shown on the Nexus 7 attached.

I was trying to do something like this. I tested out Google Drive and Dropbox, but both seemed to have issues, one of which was the file transfer rate. TOOK FOREVER. What video player do you use to watch the mkv files?

Mine has a pop up, but there's no "copy anyway" option. Just "cancel" or "ok". Hitting okay just accepts the rejection message, it doesn't keep transfer.
It is Windows Home version though, so like the other post, this may be the issue.
My tablet isn't rooted yet either.

Hi all,
When I connect my Nexus 7 to my Win7 x64 laptop the system doesn't mount the tablet to a drive letter. It's listed a simply "Nexus 7". I can browse to it, but when I show file details it looks like the OS is thinking everything must be some kind of media (like music files) because the explorer window doesn't show the"modification time". It shows instead Track Number, Artist, Album, Year, Duration.
Thinking it might be Windows Explorer I've also tried Free Commander (a file browser) and get the same results.
Anyone know of a way to get Windows to see the files as something other than music files so I can see all the normal file attributes, especially mod time? The reason I want to do this is I have a bunch of epub files on the tablet and when I get new epubs it's easiest to sort by mod time and compare what's on the tablet vs. what's on my PC and copy all the files newer than the newest file on the tablet. This worked great on my Nook Color, and would love to be able to do the same with the Nexus. Right now it's a real challenge to figure out what I need to copy.
Thanks for any help!
UPDATE: After looking around some more I discovered that Windows 7 is seeing the Nexus as a "Portable Media Player", which is probably why it didn't mount the storage to a drive letter and thinks all the files are some kind of media, thus the file attributes Windows Explorer is showing. So now I guess the question is, how can I get Windows to think this is more than just a media player, and I guess mount the storage to a drive letter like you'd do with a USB flash drive or an external hard drive?

Well, I feel a little foolish about being able to get the mod times on the files. I hardly ever use Windows Explorer so I didn't realize I could just click on the header area where it says "Name, Type, Size, etc.." and simply select "Modification Time". I clicked on that and Voila! the mod times were there for me.
But in the midst of my searching I found this thread:
http://forum.xda-developers.com/showthread.php?t=1774556&highlight=portable+media+player
which had an interesting alternative called AirDroid:
https://play.google.com/store/apps/details?id=com.sand.airdroid
It allows you to view the files on your Android device via wifi from any web browser on your PC/MAC/etc. I tried this app out and although the transfers were quite slow it's a pretty nifty way to copy files to/from an Android device, and it showed me the modification times!

When I transfer my Pics and Videos in camera mode, Windows wants to transfer my whole SD card, and wont transfer the videos I've taken. Any ideas why?
I'm using auto-play transfer on Windows,
Thanks-

I am pretty sure within windows - while the transfer is happening, there is a way to click on the transfer icon and change the parameters of what is transfered - but the way i remember it, if the transfer is quick, you can't get to these options.
For me, i don't ever use camera mode. I use Media mode, then click on the phone under my computer and browse to the DCIM folder (on card, or phone) and move files manually. But i usually don't even do that. I let dropbox sync it all automatically. It is free and i don't lose anything because i forget to transfer.
I have the auto play settings all set up. It seems to only do this with android. My wife's iPhone and our camera transfer right.
I like the way windows renames the files and puts them in dated folders.
