  • Linux and macOS support primarily through command-line tools; no native file manager integration on these platforms
  • User interface design is dated compared to modern alternatives; visual feedback and UX polish lag behind commercial archivers
  • ARM64 support limited to Windows; no ARM64 build for Linux or macOS despite growing ARM adoption
  • No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

Assistant.to

  • Its scheduling now sits inside a wider Salesforce-focused sales tool rather than being a standalone add-in
