Have you encountered a problem with a M4P file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a M4P file here. In the further part of this page we have added a list of programs that should open your M4P file. It is enough you choose a proper application for your operating system, download and install it.

Description

M4P refers to protected mp4 files that contain only audio data.

The p stands for protected, so protected. These files contain aac encoded audio data using the lossy compression method.

M4P is a proprietary version of the aac format that Apple iTunes uses for DRM (Digital Rights Management) FairPlay protected files. This DRM variant limits the number of computers and devices on which the file can be played.

In order to play an M4P file, the corresponding computer must be authorized using iTunes. The files are linked to an iTunes account and a maximum of 5 computers can be authorized with the same account data. Winamp needs a plugin to play these files.

How to open a M4P file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the M4P file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a M4P file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support M4P files. At this point we are looking for disk space where the application was installed in and we can link it with a M4P file. Since then, our operating system will use the selected program to support all M4P files.

Other issues

Despite the described problem with M4P there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the M4P file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the M4P file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
