I try running the program and get:

[dc4444]

The program '[2548] RecursiveDelete.exe' has exited with code 1 (0x1).

[dc4444]

I did not mean to close it previously.

Can you be more specific about what you are trying to do?
Obviously, you would be better off if RecursiveDelete did report why it failed, wouldn’t you?
