Very nearly all flash drives come with some sorts of small programs on them. On really cheap ones it may be just an advertisement to "buy a bigger one next time" but quite often its a "synch" program or some other sort of "file management" bit, and in any case is frequently in a "hidden folder" or is a single "hidden file."

I've had to get such memory sticks for my daughters to use at school and I've not yet seen a SanDisk "Cruzer" memory stick in Oz that wasn't sold with both a file management program as well as a partition for a 'pretend' CD.

It's quite possible, Sandra, that what JiK has written about how you may have configured your system is "the go", concerning file attributes.

Cheers, and good luck, Rowan
