File extension MDF

File extension MDF is one of the file extensions that define type of the file and its contents.

The .mdf extension format files are included as the CD Image files. They are generally related to the &qout;Alcohol 120%&qout; software:&qout; which is created by the Alcohol Software. The full form of an .mdf file is media Descriptor File. As the name of the format very clearly says, the contents of these files include a disc image, in addition to the contents which are put into an optical disc. Technically, there is always a pair of extension formats which works in such a file.

What's the use of this file format?

In the case of the File extension MDF, the second extension which forms a pair with the mdf extension is the .MDS format. Both these file formats, together form the proprietary file which is made for the Alcohol Software. Out of the two file extensions, the MDF files may contain the disc image of the data, including the core and original contents of the optical discs such as the CDs or the DVDs. On the other hand, the files with the MDS extension format are optional and are actually the descriptor files which carry the metadata information about the original media. Another difference of data handling between the two is that while the actual data in the disc is saved in the .mdf files, the MDS files may only contain the header an d track information of the file.

When implemented in practice, the format of the File extension MDF is very similar to that of the .bin files in the CUE/BIN format and also to the IMG format in the CCD/IMG format. Technically speaking, all these files are actually the raw disc images of the basic binary contents of a particular optical disc. The files saved as the disc images on Alcohol 120% are just like the .ISO files. The only difference is that the .iso files are saved in a different format.

So, how to open this type of file format safely?

The best softwares or programs to create, modify and access the files with the File extension MDF are Alcohol 120% and the Daemon Tools. The other application which are also related to the .mdf files are the SQL Server (the Master Database File) by Microsoft, Capture Classic by Accelio, Fldigi by Dave Freese, Insight II by Accelrys Software Inc. and ProWORX Nxt by Schneider Electric.
