Here's the scenario:
- I create a ZIP archive using some GUI package like WinZip, 7-Zip or whatever by right-clicking on a directory "somename" and selecting "Compress to archive 'somename.zip'"
- When the archive is completed, I open it and discover that some files don't exist in the archive (for reasons yet unknown).
- I want to find all files that are missing from the archive without having to extract the archive to another directory, then doing directory diff, etc.
Is there a tool (GUI or command-line, standalone or built into a compressor, for Windows or Linux, I don't care) that can walk through an archive and compare its contents against a directory on the filesystem?
