Notes about the S2R file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The S2R file type is primarily associated with 'RegMagiK Registry Editor' by Guzner Software. RegMagik is a registry editor. It provides an in-pane search results display, with sortable columns and has a bookmarks system, with drag and drop support to your desktop. It uses forward and back keys for navigation; and the whole registry editing process is simplified by its display of only those sub-branches accessed during a current session. Its special feature is a GUID jump capability; when a value contains a GUID, RegMagik can auto-jump to its correspondent definition key. The .S2R file contains the full path to any registry key.
