There are no temporary files during extraction. It just extracts directly to the destination files. The error "not a valid zip archive" means that the .zip has been corrupted. I would test the filename to make sure it points to a valid .zip file.

I use Delphi 4, Tzipmaster 1.52, unzipdll 152 . Obviously the same file extracted with my application installed on windows 95 or windows 98 and on my windows 2000 machine doesn't give any error. Another question: when 1) Tzipmaster.tempdir="" 2) the dll's are in the system directory Where are created the temporary files during extraction ? Thanks again.
