The MFIL file extension is for the Blizzard Software Update Format. It belongs to the Settings Files category. The format was developed by Blizzard for its games. MFIL files work on Windows, Mac and Linux. You can open MFIL files with World of Warcraft, Diablo III, and other Blizzard games.
MFIL files store settings for Battle.net updates. Battle.net manages updates and connects games to Blizzard’s servers. An MFIL file contains Battle.net configuration. MFIL files are for internal Battle.net use.
If an MFIL file does not open, the software may not be installed correctly. The file itself may be corrupted or links in the registry may be broken. Key parts describing the file may have been deleted from the registry.
You can find information on opening MFIL files and programs that support them here. MFIL is a plain text format. It has update URLs and patch data for Blizzard games.
