Whenever I copy a file from my kubuntu drive over to my FAT usb thumb drive and take it over to a windows machine, the file can be seen from windows, but will show 0 bytes.

I am guessing it has something to do with the fact that the file is being copied from an Ext3 file system to a FAT file system.

Can anyone help me with this? Is there a way to copy the file in a way that can be seen fine in windows? Thanks.
