I was under the impression the WinZip had added a Command line section. If not in the released version, then in a Beta add-on. WinZip Betas have always been first class and very stable before he lets anyone download them... (My Opinion.) Rick Glazier From: "Mark Rode" <[log in to unmask]> If you must do this from the command line, then you will need to use PKZIP25.exe, which is shareware, within a DOS Window, while running some version of windows in a 32 bit environment. This will support long file names. If you were to use the old 16 bit pkzip.exe then your long file names would be truncated.
