girish1026 Posted August 13, 2009 Share Posted August 13, 2009 (edited) In June/ July 2008 CHIP magazine Indian edition DVD, i saw a image file of Microsoft Visual Studio Professional 2008 Beta. The image size is just 845 MB only. I mounted that image in virtual drive and i checked the size of contents. That is nearly 2414 MB. How this is possible. Is there any software available to do this. Someone said that, first they compress it nearly to 35% of original size, then they convert it to image file format. If so, is it correct? Plz if anyone knows this issue let me know how it possible?Thanks. Edited August 13, 2009 by girish1026 Link to comment Share on other sites More sharing options...
DigeratiPrime Posted August 13, 2009 Share Posted August 13, 2009 What format is the image file? IIRC, ISO images don't support compression but does support 'duplicate' files, WIM images supports 'duplicate' files and compression. Link to comment Share on other sites More sharing options...
