Any explanations? I think it's a combination of both. From your findings, I'd have to assume 4dos expands the *.* before deleting and then performs a separate delete for each file (that's probably why it can tell you the names of each file deleted). Using the /q option just prevents 4dos from telling you what it deleted. -- - Mark Komarinski - komarimf@spiff.soe.clarkson.edu Credo quia absurdum est - "I believe because it is absurd" -- - Mark Komarinski - komarimf@spiff.soe.clarkson.edu Credo quia absurdum est - "I believe because it is absurd"
