I am getting this message from Archive Manager when trying to open a text file:

Could not open “users.js”
Archive type not supported.

I've tried different archive managers but not one works!

List of application I have in my machine to extract:

  1. Archive Mounter
  2. Xarchier (just downloaded but not working)
  3. Archive Manager (default one)

This is the output of file users.js -> users.js: ASCII text, with CRLF line terminators

    Just from preference or is there a practical reason for doing so?

    Thank you for the edit. Generally a .js file should be a text file containing JavaScript code rather than an archive. Could you add the output of the command file users.js to your question? (You’ll need to fill its correct path; you can also drag the file into the terminal window to fill the path automatically.) You could also open it in a text editor (like Gedit) and check if it is readable.

    What does archive manager in 16.04 do with a .js file? My Xubuntu 16.04 opens a text editor (Mousepad) when I double-click a .js file.

Archive manager programs are not designed to open plain text files.

It seems there is a bug somewhere with file associations that I've also encountered in Ubuntu 20.04 where the system defaults to opening .js files with archive-manager
