MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) is a digital, audio-coding format used to compress a sound sequence into a very small file to enable digital storage and transmission. MP3 files are the most widely-used audio file for consumers. Due to small size and acceptable quality, MP3 files are accessible to a wide audience, as well as easy to store and share.
Because MP3 files are so prevalent, most major audio playback programs support them. Simply clicking on the file will open it in iTunes or Windows Media Player, depending on your preferred platform. Users can also preview MP3 files.
Another program that can open MP3 files is VLC media player. Keep in mind that two other file types use the MP3 extension. They are Masterpoint green points data, which is obsolete; and TeslaCrypt 3.0 ransomware encrypted file, which is malware that demanded ransom in bitcoins, but is thankfully now deactivated and no longer a threat.

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.
