when I copy file.pdf to my tablet with command (in Linux - Ubuntu) cp file.pdf /media/Archos_7/Data via USB cable and then I will disconnect USB and look to the Data directory, the 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.
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.
Do you know where is the problem?
