The MCMETA file format is a plain text file used to store animations for Minecraft models. It is normally stored alongside the 3D model file in a .zip folder and contains animation timing data, such as frames, speeds, loops, and properties. The file can also contain information about the renderer used and the source textures for the model.
MCMETA files are essential for modelers who wish to add more dynamic media to their creations, and allow them to do so without relying on an external program or mod. The format is relatively easy to understand, making it easy to edit with any code editing software.
There could be multiple reasons for which the system does not support given file. In the case of MCMETA extension, it is probable that none of the installed programs support given file type. Therefore, user should undertake the following steps
If an application that supports MCMETA files is installed on user’s system, but is not used to open such files by default, right-click on the file icon and choose "Open with" option from the menu. Next, select the proper application and check the "Always use the selected application to open this kind of files" box. The system will store this information in its registry and use the selected program to open files with MCMETA extension by default.

If this step fails, see step 1.
Sometimes, although relatively rarely, steps 1 and 2 might not lead to expected results. There can be several reasons for such situation to occur:
