Opening M4P files

Did your computer fail to open a M4P file? We explain what M4P files are and recommend software that we know can open or convert your M4P files.

What is a M4P file?

Files that contain the .m4p file extension are audio files that have been downloaded from the iTunes Music Store onto a user's computer. M4P files are protected AAC files that use Apple's "Fairplay" DRM copy protection technology.

THE M4P file format limits the number of computers that a user can play a specific file on. If a user wants to play the M4P file on their computer, the computer must be authorized using the Apple iTunes application. A user can authorize up to five different computers using the same iTunes account.

If a user wants to play the file on more than five computers, he or she must create a second account. When doing so, they must purchase the song with that account, allowing another 5 computers to access the song.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
