Notes about the A2R 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 A2R file type is primarily associated with 'KittyXplorer' by MyPlanet Software. Feel safe, no one can tell what data you have encrypted with KittyXplorer. Any file can be encrypted so no one can be sure what the encrypted data are. Files are put together in encrypted archives, where the individual file data and paths cannot be seen. No one can tell whether an archive contains several images, or a big video file, or just garbage.
