Hello, Thank you so much for Universal Extractor. I really appreciate your great work. I would like to associate XPI and JA files (Firefox add-ons and omni.ja, both in ZIP format) with Universal Extractor, and add the following entries to Windows Explorer's context menu: 1) Compress to "FileName.xpi" 2) Compress to "FileName.ja" Could you please add these options? A better option would be adding a user-defined file extension for a supported format (i.e. Compress to "FileName.user-defined"). Regards.
