i've tried 7zip, winrar, winzip, all to no result, in winrar and 7zip they say archive not found, but when i open the first (and only) file with valid .zip extension using winzip all the files are there (at least the heading are), but during extract winzip ask to insert the spanned disk into the driver, which is confusing since i have the spanned files and not disks. All so confusing :-(
