Back up one (and only one) folder

[jdonth]

Rookie here. How do I backup just one folder (not the sub-folders)?

I want to backup one folder on my system (C:\Devel).
If I put "c:\Devel" in the left pane and leave the included files a "*", it does all subfolders.
If I put "C:\" in the left pane and included files to "\Devel\", it still does all subfolders.

Exclude "All subfolders"

I added "\*\" to the exclude and that worked. Thank you.
