Hm! damn bloody angry with my nexus7 today.

I want to copy a folder that has like 300+ songs from nexus7 to my laptop.
plug original USB cable. enter MTP mode.

drag the folder to desktop.
it copied an empty folder. WTH?

open the folder /kugou/download
highlight all 300+ songs, drag to new folder on my desktop.
i copied more than 5 times. it randomly stops and only copy some of it.
sometimes i get 50+, sometimes, just 150+, highest i get is 190+ songs.
it JUST DUWAN TO COPY ALL!?

if i copy all, and paste again, thinking it will just skip the ones already copied, and copy the ones left out.
but it DOEST. it says some file same name exist, skip all? if press yes it stop the copy process.

STUPID STUPID STUPID MTP mode.
in the end use airdroid to copy, speed about 700kBps, much slower than USB.
but at least it can do it.

Whats wrong with MTP?
seems got some problem.

it caused my laptop explorer.exe crash twice, need restart the explorer.exe.
never happen on my S2 with usb mass storage mode, man i hate MTP.
Is my unit faulty? MTP suppose to behave like that?

i installed and tried the software.

i navigate to nexus7 folder, use the 'pull' function to copy the folder.
just like MTP it copied an empty folder.

if i go into my folder highlight all and pull.
it says fail, file not exist something. 
attach sceenshot for you to see.


i'm begining to wonder is it because the songs are in chinese language.
this is really a  moment for me. all these time android boasting about being good in transfer file.
but i'm facing this kind of shitty problem.

worried duno is my unit problem or MTP memang like that.
this is the first time i want to move large collections of songs outside my nexus7.
usually i just transfer small stuff in and out using mtp.

I use app called battery. I check the under status one it is same.

So its normal?
