How to add Asar plugin to 7-zip

The Asar7z distribution package is an ordinary Zip archive that contains the following three files:

  • Asar.64.dll – the 64-bit version of the plugin
  • Asar.32.dll – the 32-bit version of the plugin

To install the plugin into the 7-Zip installation folder. (C:\Program Files\7-Zip)

you need to create the "Formats" subfolder.

After that, copy Asar.64.dll or Asar.32.dll (depending on your 7-Zip edition) to that subfolder.

If you do that, each time you launch 7-Zip, it will automatically find Asar7z and use it when opening .asar files.
