HOW TO MAKE DISC IMAGE USING DAEMON TOOL

DAEMON Tools is a small but powerful software which is used to make disc image and mounting disc images in virtual drives( created by itself). Using this you can make exact boot-able copy of windows or other operating systems, game CD/DVD etc.
It can create disc images of following formats:
.mdx
.mds
.iso

And it can mount disc images with following formats:
.mdx
.mds
.mdf (Media Descriptor File)
.iso
.ccd (CloneCD)
.cue
.isz
.cdi (Discjuggler)
.b5t (BlindWrite 5)
.b6t
.bwt (Blindwrite)
.nrg (Nero)
.pdi (Instant CD/DVD)

DAEMON Tools Lite is available with free license for home use only, for commercial use you have to buy this software.To download this software pls visit its official site "http://www.daemon-tools.cc/eng/home".
