# Copying files to tablet with Android

When I copy file.pdf to my tablet with the command (in Linux - Ubuntu) cp file.pdf /media/Archos_7/Data via USB cable and then disconnect USB and look to the Data directory, file.pdf has size 0 B, or the file is not there (e.g. file.epub). I don't know what is wrong. I copied a few *.pdf and *.avi files successfully.

Do you know where is the problem?

Now, I copied three files - file.avi, file.pdf and file.epub to the Archos_7/Video folder. file.avi is copied OK, file.pdf is copied but has size 0 B, file.epub is not there. –  xralf Mar 15 '11 at 21:13

It was needed to umount. –  xralf Apr 22 '11 at 10:48
