Notes about the MFS 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 MFS file type is primarily associated with 'MetFS' by EnderUNIX. MetFS is filesystem software in userspace that is FUSE based, encrypted, dynamic sized (increase when new data added, decrease when data removed), single file when it's unmounted. No data stored on an encrypted partition can be read without using the correct password. Until decrypted, a MetFS partition appears to be nothing more than a series of meaningless data. The .MFS file extension is associated with the MetFS program but it is not required; these files can have any file extension or no file extension. The program does not care.
