Extraterm already has some built in support for transferring files using its show and from commands but the current implementation is closer to a PoC than a robust system for moving data around. It is just enough to move bits of text around. What is needed is a full implementation which supports large files, is robust w.r.t. possible interference (think background jobs writing to the terminal), and is also binary safe.

• Spooling large files to disk
  • Basic support
  • Flow control
  • Encrypting data on disk. This is needed to prevent Extraterm being a litter-bug with potentially sensitive user data.
  • Deleting data from disk when it is no longer needed.
  • Cleaning up previous data on disk. Needed in the case that Extraterm exits in an ungraceful way. Moved to Detect any old temporary files and clean them up automatically #74
• Exposing large files via a pseudo web protocol to support streaming to the DOM
• Robust detection and handling of interference and unexpected crashes and exits at the remote end
  • Downloads via show command
  • Uploads, via from command
• Downloaded file viewer
• Streaming support in the viewers
  • Image viewer
