USB Thumb drive

Hi Suse 11.0 rc1,
I had some files on my thumbdrive that I moved to the desktop to make room on the thumbdrive. Now I want to move them back to the thumbdrivem But I can’t.
Why and how can I do it?

what file system format is the drive? what error do you get?

I think it’s a fat32. I get no errors. When I try to drag a’ drop it (the file) goes under the open dolphin window
I used 11.0rc1 to remove those files.

try running (in a konsole/terminal)
‘cp -R /path/to/folder/or/file /media/devicename’
