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.

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.

Here's how to use the .mdf file. Alternatively you can use alcohol 120% to mount the .mdf then use it to copy that drive into an iso!
To burn the .mdf either use a program that burns them to a disc or do the opposite of the above procedure to get and iso. Then burn the iso onto a disc!

Here's what I do....

I use Daemon tools (google for download) to mount the image on the computer and then i run it.

Break it down....

Install Daemon. Run it. Right click on the icon in the system tray (the set of icons in the bottom left of the screen with the time in) then go to virtual cd/dvd-rom then whatever device you want to use then mount image and browse to the file then press ok. Now open up my computer and it will say there is a new cd drive and that it has the disc you just mounted in it.

What did I just do????

You just got Daemon tools to trick your computer into thinking there is another cd drive with the disc in! This is useful if you have a game and have lost the first disc. Normally this would mean you can't play it, but with the mounted disc you can then play it without needing disc 1! Also means you don't need to find the disc when u want to play the game!

Look, this is all explained in like the third post here. Alcohol 120% does not technically support MDF files, but if you go to mount the virtual drive and change the type to 'all files' the MDF files will show up and you can mount them anyway. From there, if desired, you can copy the virtual drive to a more common image format or to a physical drive. That's all
