7-Zip plugins\Asar7z

Asar7z is a small plugin for the popular 7-Zip archiver. You can use Asar7z with 7-Zip to open, modify, or create .asar archives, which are used for packaging applications based on the Electron framework.

Open asar in 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
  • ReadMe.txt – the user instructions

To install the plugin into the 7-Zip installation folder, 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.

Usage notes

When packaging their applications, some Electron app developers may create encrypted .asar archives. You cannot access the contents of such archives unless you know the specific encryption method.
