Ok, I tried now:

Code:
WScript.echo TheFile

FSO2.DeleteFile TheFile, TRUE

WScript.echo TheFile & " is deleted"
No error comes up.
And the second echo doesn't say anything.

This is all what comes out:

***** script completed - exit code: 0 *****
Remark:
The files in question are accessible and deleteable...
