Uses
-
MDF files are used primarily to backup exact copies of original discs. For example, if you wanted to backup a computer game, you would create an MDF file. Note that MDF files can be burned onto a disc, which is not true of all file types. Note also that while the actual disc data is stored as an MDF file, any header and track information will be stored as an MDS file.
