Opening M4R files

Did your computer fail to open a M4R file? We explain what M4R files are and recommend software that we know can open or convert your M4R files.

What is a M4R file?

Files that contain the .m4r file extension hold custom ringtones that have been created for the iPhone mobile device. These ringtones are created with iTunes and can only be created from songs that have been purchased from the iTunes Music Store.

Not all iTunes Music Store songs can be used to create M4R ringtones. In order to create an M4R ring tone from an iTunes song, the song must allow for M4R ring tone creation.

Some M4R files can be created with third-party software applications or may be downloaded from the Web. These files may not be copy protected and can be played on other media devices.

An M4R ring tone is automatically transferred to a user's iPhone when the iPhone is synced with the user's computer.

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.
