If you are still wondering:
- What is the breakdown of that 32GB Xoom internal memory (how many parition, how much space for apps / files)?
- Why Google is using MTP instead of USB file transfer on Honeycomb?
Here is straight answer from Google developer:
MTP is a big improvement over USB mass storage — for devices with lots of internal memory, a manufacturer no longer needs to come up with some hard partition between the USB mass storage and internal storage. Instead, they are all in one partition, with MTP providing access to the directory of media files that would normally be available through USB mass storage.This means there is no longer a need for apps on SD card for such devices, because what used to be the “internal SD card” is in the same partition as where applications are stored. The storage on your device can be used for either applications or media, depending on what you want to put on it. You aren’t stuck with how much space the manufacturer decided to leave for the two areas.
Oh also this means that the media storage doesn’t need to be unmounted from Android when it is being access through the PC.

Finally, true APP2SD You now have 32GB to put all your apps!!!
Sounds like a good thing!
This is a great explanation. Thanks for posting.
There is no doubt that mtp has advantages over mass storage. On the other hand I miss the ability to attach it to any computer and access files. It is not a huge problem but does add a limitation that was not there before.
That saod it is nice being able to access files on my computer without losing access to the partition on the device.

I'm sure future versions of CWM will be set to ignore that one folder.. I hope. Otherwise nandroid backups will take forever.
I'm not sure in terms of security it is a huge improvement; unless there is an option to turn it on/off somewhere.
Previously I would have to plug an Android device in to my computer, turn the device on, enter my unlock code, and then specifically allow the computer access via the USB. This morning I just plugged my xoom in and, poof, access to all my stuff.
At least before someone had to take my sdcard out at put it in their computer manually
Does MTP have anything to do with file size limit? I've seen posted on this forum that you can't load video files larger than 4gb onto the Xoom because of FAT32, is that still the case?
This MTP also seems to hide a lot of file from being seen by a pc. I open folders with File manager on the Xoom and see more folders namely the android folder which has game save data and other odd ball files. When hooked to a pc its blank. With MTP it seems all your allowed to do is transfer music, video and pics.

Still haven't got around to testing (so many things to try out!), but in some of the video threads, I've been told XOOM uses EXT4 format not FAT32, and thus, should not have that 4GB limit. I've been re-encoding video files to meet XOOM's current playback limitations, and have been reducing them to sub 4GB anyway, so I haven't tested that for myself.
Still no sdcard slot!
Still no USB On-The-Go memory device support (we have USB joystick support but still no memory devices)
I haven't tried abusing the Camera Connection Kit yet to see if I can use a camera as a memory card reader.

It's never been a problem. 3.x and higher use MTP so they can stop using FAT32 for internal storage. Linux does MTP just fine. What are you talking about?

why was this method needed? Xoom will not show up as a drive, unless you do this. Where as with the Droid X, once plugged in, it showed up as a drive. I hope this makes sense.

USB Mass Storage is the old method and it shows up as a drive. The Droid X is older than the Xoom therefore it is using USB Mass Storage.
MTP is Media Transfer Protocol and is the method used by 3.0 and higher.

Hmmm, from Android Honeycomb 3.1 Details ...
...Android 3.1 still isn’t intended, at the operating system level, for managing external storage devices. This detail, which came out in conversations I had with Google engineers today, explains why the Android file system organization is, well, a mess...
“We don’t want to expose the user to file locations,” explained Hiroshi Lockheimer, director of engineering at Google. “How do you manage that as a user? The not-good answer is with the file browser.” Lockheimer says that many of the experiences I’ve seen so far are what individual hardware manufacturers have enabled, as opposed to what Google has provided natively. The good thing is that Lockheimer says Google is looking at ways to do this; but the problem hasn’t been solved yet...

He did answer you. The xoom uses mtp which will not show up as a drive in Linux unlike older android which used mass storage. Mtp allows you to add files with out having to unmount the file system on the xoom. There are many threads on how to set mtp up. If you're new to Linux it may seem hard to do but its simple. Do a Google search for mounting xoom Ubuntu and you should find them easy.

totally agree. there are lots of things i understand why they're waiting, but this? come on. i could clear all on my phone.
I just want to clear up a misconception about MTP. It is not a cross platform solution for transferring files.
My post from another thread on the subject:
I can mount my Xoom in linux using libmtp and mtpfs, however, it's slow, kludgy, and generally feels like it will flake out at any moment. Additionally, even when it's mounted, I can't seem to copy music across properly; it doesn't keep the folder structure. In fact, the directories are created and any non audio files are copied across fine, but every mp3/audio file is flatly dropped into the Music directory.
I tried to copy some music onto it from my fiancee's windows xp laptop and it worked ok (though the album art didn't appear).
The move away from mass storage to MTP is a massive disappointment for me. Mass storage has always been a big selling point for me when purchasing a device and for Google to switch to using a Windows specific protocol and consider it cross platform is a big letdown. MTP on mac requires a special app and on linux, support is dire, certainly for anything more complex than simply pulling images from a camera.

I can just about get files onto the xoom, but I can't load music onto it; all of my mp3s just land up in the top level of the Music directory, regardless of how I attempt to transfer the files. I think transferring a zip file of the music and unzipping from within a file manager on the xoom might do the trick, but this isn't a good, workable solution. I understand the reasoning behind MTP, but it most certainly isn't cross platform and shouldn't be mentioned as a working solution by Google.
Hopefully people will soon realise not to keep insisting that the xoom has linux support when using MTP.

Change all the extension names in the song file name to .mp and it will allow the transfer
Then use something of your liking, I use astro file manager, and just add the 3 on the a tail end of the extension.
Its a b, but you can at least get a couple good songs on there.

You're right, it's a cross-platform solution for transferring MEDIA, being the Media Transfer Protocol.
It's smart enough to detect the media files that it supports and put them in the right place. I prefer it over the old way, I hated having to unmount the sdcard every single time.
A poorly made Linux MTP library doesn't make it not cross-platform. It's an open standard for transferring media to USB devices.
It's not perfect, but it's great for a device like the Xoom where unmounting the internal memory is not desirable.
Honestly users get really confused by all of the extra directories when mounting an android sd-card anyways.

Actually, it has been a big debate on rather it is Google's or Moto's issue, but I am sure that we all can agree that it needs to be fixed no mater whos issue it is.
This is a list of all the options I tried (in chronological order) to solve my file transfer issues with the Galaxy Tab 10.1. The last option is the most stable one and until either Samsung or Android give us something usable I'll keep using it. Its a WiFi solution, so its slow in comparison to a USB solution.
Kies Software: Simply does not work for me since it requieres the USB drivers to be installed and for some reason they will not install correctly in my laptop.
Kies via Wi-Fi (Settings/Wireless and networks/Kies via Wi-Fi, it requires the Kies software): It says that the SIM card was not detected... There's obviously something really wrong with that Kies app because I have a WiFi only tablet...
Kies App: Basically creates a server in your tab that you can access through your browser. It works but if you need to transfer several GB's of music files organized in folders... you're going to have issues with it... Plus its really unstable.
SwiFTP FTP Server: Basically creates an FTP server in your tablet that give you access to the whole disk. It works with any FTP client in your computer. I use FileZilla. Its realy stable and you can simply drag and drop all your files to your FTP client. Also, it doesnt interfere with the use of the table. So you can use it while the files transfer. There's more options for FTP servers in the market but this one works, so why bother...
I hope this thread help you guys!

If you have rooted your Tab, there is a free app that is so simple a US Congressman could us it. Check out Samba Filesharing. It makes your Tab's SD drive show up as a wireless device on Windows computers. It is fast and easy as drag and drop.

I haven't used my USB cable for transfers since I got this program in August. Dev is awesome, will help those that need it, and he updates the program with new features about once a week. Best 99c on the Market.
Another option is Airdroid. Search for it in the Market.

had similar problems and removed KIES and installed Airdroid on my tablet and works great!
kies air is not an option when you have to transfer more than a couple of files.
I only found the option to transfer one at a t ime through the web interface.
so it is extremely time consuming to do 1 at a time...
The best option i found so far, was the como with the adaptor for usb sticks and flash cards.
I got it on ebay for about 25$ and i been using it all the time since then.
It is VERY fast (depending on your usb stick as well) but with a trancent stick, i get about 10~15 secs for 1GB of mp3s.
So far it is the best way i found to transfer files.
P.S. I believe it is a lot faster than using the cable usb connection with the included charge/data cable.

How is this better than MTP? I connect my Note and it shows up - I double click on it and it shows me a drive for the internal and external storage and you can drag file in and out of them. The only two issues are that when you copy some kinds of media, you get asked if you want to convert it - and on the Note, it runs an actual app to do the MTP. It's odd because other Android devices don't do that (even the Samsung Nexus doesn't).

If you use other OSes then Windows you will notice the difference, it does not work reliable on Linux and Mac. MTP is slow , with UMS i get something about 20MB/s read/write. Also, if you have to modify a file then that file will first be downloaded locally on your PC, modified and the reuploaded instead of modify it on the phone. This is how MTP works.
I have used the app 10 times by now, no issues at all. I also checked the sd card with scan disk on win7, no corruption !
By the way, there's a good technical reason why modern Android devices don't do USB Mass Storage.
USB Mass Storage operates on an *entire partition* and needs *exclusive* access to that partition. So the phone needs to be able to totally *un-mount* the partition (stop using it entirely) which is to be mounted as USB Mass Storage.
Older devices like my Samsung Galaxy S2 had the built-in storage separately partitioned. The downside to this, however, was that app storage was on a small, limited partition so even though the phone had 16GB, apps were limited to a 2GB (or so) partition.
New devices have all data on one partition so the app data can expand as far as it needs to into your storage space, but it means that it's no longer possible to mount it over USB Mass Storage as you can no longer get exclusive access to a partition.

You are right about internal storage, but , this app only exports the External SD Card, which is formtated as FAT32 or ExFat. The app first unmounts the card from phone, export it through USB, then with the middle button, when you are done on PC (end ejected the card), will mount it right back.
This way you could check the SD card on the PC, copy large files very fast, directly modify files, works on linux and mac !

Another weakness in MTP is that if you are in a locked down environment with no admin/privileges to install devices MTP will not be detected. (You'll get the same nonsense with iOS as well)
has anyone been able to get this working with a ps3. I would like to be able to transfer things to my ps3.
So, no method exists that would allow the Note 10.1 to connect as UMS to Windows XP? and/or without the use of the inserted MicroSD?
I installed KIES but it tried to install like 3 versions of Net Framework and other garbage, so I removed it. There is no way I will use the KIES. I tried to use the driver that Kies installed along with the SAMSUNG_USB_Driver_for_Mobile_Phones.exe but no luck. I can't believe this is an issue.
I'm a bit of a novice with tablets/android and have searched a long time for a solution with no luck.
It only export the external sd card through UMS, the internal one it is impossible. For me, it works on XP x64 just fine.
Has anyone tried multi mount, i use it on my galaxy s to listen to music while i am mounted to the pc, works well but i think it a bit buggy cause i can't get my external sd card to mount but i don't know if that the rom cause it worked well on the previous rom, try it out multi mount

This is about the lack of storage. Everyone seems to be happy with the plugging in of the usb and removing it whenever it is not needed.This to me seems long as you have to pen a file manager to see your files and obviously cannot install apps on it. I was wondering if we could put the actual android os onto the stick so we boot the phone off of it so we can also install apps? Just an idea.

For that to work you would need OTG working, it isn't supported currently. Even the 8GB model has more than enough storage for system files, apps and their associated data; its people that like to carry around huge music or video libraries that find it inadequate. BTW box.com is offering 50GB of free storage for any LG phone this month, embrace the cloud people.
