cm_CopyFullNamesToClip lacks one Backslash after Drive:\
Should be Drive:\\
The drive letter is lower case, shouldn't it be upper case?
OS: Windows XP Pro 5.1 (Build 2600) PostSP2
File system: NTFS
EDIT: Oh sorry, was a bit confused because I play around with C# and got an error message where the path starts with C:\\...
Now I see, that even in Windows Explorer there is a single backslash behind the : and remember it.

Can be deleted...
