What is the .MET File Extension?

.MET File Extension Description:

The file extension MET is used by several applications for different purposes. One of the programs utilizing the MET file extension is the Microsoft Flight Simulator. It is a very popular game geared exclusively towards flying enthusiasts. The other one is the eMule Project software, which is actually an offshoot of its peer-to-peer predecessor eDonkey.

The files with the .met extension used by Microsoft Flight Simulator 2004 serve as archive files for the weather engine and sky graphics. The files having a .met extension are accessed and have their content loaded for specific saved game states of players, complete with current location and flight dates. It also includes the in-game log file of the flights taken, with their corresponding environment sprites setting. A rather primitive format, the MET file extension has been replaced with a newer archiving system on the more recent versions of Microsoft Flight Simulator.

The other program utilizing files with the .met extension is eMule Project, a commercially distributed peer-to-peer program. The said program allows the user to share and exchange files with other eMule Project users. The file extension MET serves as a cache information file. This serves two functions, both for the client side and the server side.

On the client side, files with the .met extension function as meta-data archive files. This allows third party programs to properly identify a file as part of a bigger chunk and then access it without requiring the remaining file parts. This is especially helpful for programs that need to play segments of videos without having to complete the bigger file.

On the server side, the MET extension provides access to the eMule servers and to the ed2k network. This allows users to actively post and share their files, as well as search and download files from others.
