Deleting a Folder

I have a folder “Angel…” that is created from a chat software trillian. Let assume that this folder is located at “c:\Angel…”.

Basically, the software would create a folder based on the screen name for any file that I download from that user. Unfortunately, when it saved under that folder, the folder is inaccessible, can’t be deleted, can’t be renamed or anything.

FYI: I’ve tried “command”, “cmd” and I can’t load from a diskette because I have NTFS file system under Windows XP.

Question: How do I delete the folder?
