The .asar extension files are files used to package source code for applications that use the Electron framework.

The easiest way to unpack these files is by using 7-Zip and a plugin called Azar7z that you can download for free from their official site.

Installation of Azar7z


First we go to the installation path of 7-Zip (I assume you have it installed) depending on your operating system.

Inside the same folder (C: Program Files 7-Zip) we create a new folder called ‘Formats’.

Now we download the plugin from its official site, and this is a .zip file, which when unzipping leaves us two files Asar.64.dll and Asar.32.dll.

If your 7-Zip is 64-bit copy Asar.32.dll to your Formats folder and you’re done.


If you have any doubts about the 7-Zip version you have installed, just open the 7-Zip File Manager and go to Help-> About 7-Zip … and locate the software version.

Now if your 7-Zip is 32-bit copy Asar.32.dll in the folder ‘Formats’.
Now your 7-Zip will be able to open, unpack and package .asar files.
It is not 100% safe since sometimes protect these files with password, same that you must provide.
