What is an *.MDF file?


If it is a rather large file, e.g. 650 MB, then it is most likely a CD image. If it is a file of smaller size, see at the end of this article. These MDF image files are created using a CD/DVD CD/DVD image file editor (and CD burner and CD/DVD backup tool) called MagicISO Maker.
MagicISO Maker can directly create, edit, extract, and burn ISO/MDF files. It also can convert almost all CD/DVD image formats to ISO/BIN/CUE, Nero (.NRG), and CloneCD (.CCD/. IMG/. SUB). With MagicISO, you can handle DVD image up to 10GB; make CD image files from CD/DVD-ROM; also can burn ISO files and other CD/DVD image files (BIN, IMG, CIF, NRG, BWI, VCD) to CD-R/RW; support loading boot image file exported by WinISO and UltraISO; burn CD image files in ISO9660, Joliet, and UDF format; edit properties of CD/DVD image files; it has the ability to correct volume serial number after editing original CD/DVD image file; search files or directories with wildcard characters in CD/DVD image file.

You can download it here:

Not a CD image file?

If you cannot open your MDF file with Magic Iso Maker, then it may be a database file. dBase used to store their memo fields in a separate file. Regular tables were stored in *.dbf files, memo files were stored in *.mdf files.

SQL Server 2000 creates MDF files as well.

Okay will someone fucking answer this? I downloaded a game for the epsxe emulator. I open the folder, and it contains two files, .mdf & .mds . I extracted the data from the .mdf file using either magicISO or some other program. There were many different files. So, after extracting, I tried to run the only .img file on my epsxe, but it only came to a black screen. Wtf am I doing wrong?! Could someone PLEASE help me?

ok people it seems like there are a lot of problems here... im to lazy to go through to see if they are answered and just want to help. Since your downloading illegally anyways... find a torrent for a newer version of 'Alcohol 120%' drag the MDF (the really big one) and the MDS (the tiny one) into the alcohol window. there is usually 1 mdf and 1 mds per disc of the game/program ur downloading e.g.- Black & WHite 2 is a four disc game.... i should have a disc 1 mdf, disc 1 mds, disc 2 mdf, disc 2 mds, disc 3 mdf, disc 3 mds, disc 4 mdf, and last (thank god) a disc 4 mds. Get only one disc worth of files in alcohol at a time (so disc 1 mdf and disc 1 mds) you should only see an mds file in the window but unlike regular mds files it will be the size of the mdf (genereally big)goto burn a CD/CD-ROM/DVD and burn the mds file to the disc.... when your done... congrats!!! you burned the first disc of your download! Now a lot of people are going to say... well i wanna play without the cd... well if its a game you can just go to and search a 'No cd patch' this will allow you to play without the cd. well im out

Right if someone could help would be great, i followed the steps in post 2 by sex monster.

The file i downloaded is a Rar file that contains an MDF and MDS file, when i try to browse for the file to mount it will only show the Rar files after selecting show all files.

I have tried these and when i click on the Drive E its says 'file may be corrupted etc'

I have also tried to convert the file using UltraIso again it does says 'unknown image'

I might be asking a really stupid queston here but can someone help.

Please help!!! I just downloaded the Command and Conquer : Tiberium Wars game,
it came with 3 files CNC3.MDF CNC3.MDS and a file with stuff in it. The mdf file is about 8 gb and the mds and zip file are very small. I tried opening the zip file and it said it was like corrupted which sucked but I doubt the other two files are broken.. well hopefully. I Downloaded the DAEMON TOOLS and mounted the mds file (mds only showed up w/ default settings i tried mounting the mdf but made no difference) and tried to double click it in my computer to run it, but i got 'windows cannot read from the disk, the disk might be corrupted or using another format that is not compatible with windows'. Well does any have ne ideas w/ what i should do?? I dont have a DVD burner so i can't burn the files so Im trying to mount them yet i have no idea what im doing. DO i need to download any other applications or drivers to run a mounted file. is there a way i can extract / install the mdf file using another program and if so how.. well thanks, please help me out i spent like 2 days downloading it and i hope it wasn't a waste!!!!
