Zip stores the RMS file attributes and record attributes for each file in the archive, but only when the /VMS qualifier is used to create or add files to the archive.

If the /VMS qualifier is NOT used, or if the /PKZIP qualifier is used, Zip will attempt to convert the files being archived to a format which is common to the bulk of the non-VMS operating systems supported by Zip.

Next, we’ll discuss some non-VMS operating systems and their file characteristics.
