The MUP file extension refers to Music Publisher Score files. These files are data files created by the Music Publisher software from Braeburn Software. Music Publisher is a music notation program for Windows.
MUP files contain the digital musical compositions created in Music Publisher. The compositions are saved as text using a proprietary syntax that represents the musical score. Composers can modify and refine the MUP files as needed. MUP files can also be printed out as sheet music.
Out of all MUP files, 1% use the ZIP format internally. So 1 to 5 files are compressed and saved together in one MUP file. These ZIP-formatted MUP files range from 1KB to 24KB in size, with an average of 2KB. The remaining 99% of MUP files have no uniform format.
Some MUP files associate with pyramid schemes. Others associate with gateways. Over 1300 different file types use the MUP extension across various operating systems. So MUP files have a typical data file structure.
When trying to open an MUP file, ensure the application is up to date. Old versions may not support the latest MUP format. It’s also good to scan MUP files for viruses before opening. Recommended antivirus software includes Norton, Nod32, Kaspersky, and Dr.Web.
