read the list of files contained in a zip archive
string (zip archive filename)
The Contents command reads the index of a zip file archive and returns a list of strings representing the names of the files contained in that archive.
The list returned does not include the zip file name. To read each member, L[i] returned in the contents list, use FileTools:-Compressed:-ReadFile( L[i] in zipfilename, options ).
This command only works on zip files. Files in gzip format do not contain sub-files.
The filename option must be a string, not an open file handle, and not a subfile in zipfile member reference.
