title: Remove metadata from 7zip files
body: <p>If two files with the same checksum and name but with a different created or modified date are compressed using 7zip, using the same settings, then their checksum will be different. I understand it's because of metadata. Is there any way to tell 7zip to ignore those metadata, so that their checksum will be same regardless of their created or modified date? I don't see any command line option in 7zip to do so.</p>
  
  <p>Thanks</p>
