.S2R File Extension

What is an .S2R file?

The s2r file extension is associated with the RegMagik, an enhanced Microsoft Windows system registry editor developed by Boris Guzner.

The s2r file stores some kind of data used by RegMagik.

Probably not meant to be accessed by the user.

Probably cannot be converted to anything else.

Associate the S2R file extension with the correct application. On :
Windows: Right click on any S2R file and then click "Open with" > "Choose another app". Now select another program and check the box "Always use this app to open *.S2R files". Mac: Right click (or Ctrl-click) the S2R file, then click "Open with" > "Other...". Then choose another program and check the "Always Open With" box. Linux: Right click on the file, and select "Open with" and choose another program. iPhone: Tap the file. If you do not see an app to open the file, then tap Share "Share" and choose an app. Alternatively, save the file. Then open the Files app Files app. There long-press on the file, then release your finger. You will see a black menu bar. Then tap "Share" and select an app. Android: Tap the Settings icon on your smartphone, then tap on the Apps section. There tap the Options icon in the top right-hand corner of the screen to change the default apps.
Update your software that should actually open .S2R is RegMagik data. Because only the current version supports the latest S2R file format. Search, therefore, e.g. on the Boris Guzner manufacturer website after an available .S2R is RegMagik data update.
To make sure that your S2R file is not corrupted or virus-infected, get the file again and scan it with antivirus software.
