List of filename extensions / M

from Wikipedia, the free encyclopedia

This list contains common file name extensions that are used in some operating systems to differentiate between file formats . In other operating systems, file type identification is mainly carried out using the file header, and the MIME type is more important than the file name extension for e-mail attachments . Systems that use the latter two approaches usually ignore the extension completely.
