Apple iPhone Ringtone (M4R) is the file format Apple uses to store ringtones on iPhones. The maximum length of an M4R file is 40 seconds. The only difference between M4R and MPEG 4 Audio (M4A) is the file extension, which lets an iPhone know M4R is a ringtone instead of a song.
As a format deployed by Apple for iPhone ringtones, M4R files open on iTunes by default.
Alternatively, Apple iOS is another good choice for opening M4R files. To create a custom ringtone, simply save an M4A file as an M4R file, and then import it into the iPhone.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.
The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.
Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
