File Extension MUF

File type: Temporary Access Control File

The MUF file type is primarily associated with 'Alpha Five' by Alpha Software, Inc.. MUF files are temporary files that Alpha Five creates to control the number of people who can concurrently open a database. If a user has a 3 user a5 license, then: when person 1 opens the database, the .MUF file with the same name as the .ADB file is created and a count of 1 is recorded in the .MUF file. When person 2 opens, the count in the .MUF file is increased to 2. When person 3 opens, the count in the .MUF file is increased to 3. When person 4 tries to open the count in the .MUF file would exceed the number of licenses, so person 4 gets an error message. When person 3 closes, the count in the .MUF file is reduced to 2 and person 4 could open. When all users close the count in the MUF file is 0 and the .MUF file is deleted by Alpha Five. If a crash occurs the .MUF file may be left on disk, preventing other users from accessing the application. In this case all users should exit Alpha Five and the MUF should be manually deleted.

When windows gives you an error message saying that it
"Cannot open MUF files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

In both cases it is strongly recommended that you
run a free scan for registry errors.
