How fast are you willing to get those folders created ? I'm saying this because you could use the system time, in milliseconds, to name those unique folders. If you want to avoid the possibility of having two or more folders on the very same time, concatenate some string at the end.

Why is an MD5 like

A4-B7-81-7F...

invalid? Have a look at the BitConverter-class

Can't you just use a Guid?

String folderName = Guid.NewGuid().ToString();

Why not just remove, replace or encode those invalid characters as valid ones?
