We have a process whereby Arev converts documents 10,000 cases at a time (each case could possibly have multiple documents) into HTML documents. These are individually gzipped and the lot zipped into a single ZIP file prior to ftping to a unix machine where the .gz files are extracted from the zip file. Each zip file contains an index file that lists all the .gz files.

The problem we are now having is that there seems to be some gremlin in the works that is aborting part of the process so that the zip file contains only a portion of the .gz files. There is a check that takes place in the process that looks through the index file and checks for existence of all the .gz files. If they are not all there, the batch is flagged as having a problem.

This check takes place after the .gz files have been extracted and distributed on the unix box. I would like to add another step to the process that can be kicked off by arev that would generate a file list from the zip file just created and compare it to the index file. If there is a mismatch, the batch is reprocessed BEFORE ftping to the unix box.

At the inception of the project, we looked around for various tools to accomplish this task and settled on WinRAR. But we don't create .rar archive. We create .zip files using WinRAR. The reason we chose WinRAR is that it can be kicked off from Arev efficiently and has no problem handling large numbers of files like this.

The problem is that there doesn't seem to be a command line option to generate a file listing from WinRAR. There is a companion utility, RAR, that does have this ability, but I can't get it to work on .zip files, so I suspect it only works with .rar files.

Can anyone offer a suggestion for another application that we can use simply to generate a listing of the contents of a list file? The utility must be able to handle 10s of thousands of files. It must be callable from Arev and run on Windows 2000.

Winzip has a command line interface. See http://www.winzip.com/prodpagecl.htm

Thanks. I'm looking into that to see if it's something that will work for us.

So does PKZIP for DOS.

PKZIP cannot handle that many files in an archive – unless there is a recent version that doesn't have the restriction of the version I tested a few years ago. Of course, at the time I tested, I was more interested in creating zip files, not extracting file listings.
