#How to compress iso archive

You can download a freeware called MagicDisc ( from the same site ) using which you can compress ISO images into UIF format ( Universal Image Format ) which are much smaller than the ISO and can be directly loaded into a virtual drive.Д¬ompresses ISO images to DAA format ( Direct Access Archive )Д«oth DAA and UIF files are about 40 % smaller than ISO and can be directly loaded into a virtual drive, and accessed without decompressing.ДAA is better ( faster & better compression ) than UIF All duplicate file copies will be written to CD only once. 'the same files are only allocated once'. If you want to create such a cd ,you can try MagicISO makerДЄfter creating a cd image go to File> properties > optimise and check the box When you copy such a CD to your hard disk, multiple copies are created ( one copy in each of those folders ).

In some CDs the same file can be displayed in many folders even though only one copy is written to the CD file system.

#How to compress iso software

I can't seem to find the 'Drive Image 7' application anywhere, I've read a lot of reviews on different software to backup your 'System' HDD and Drive Image was highly recommended, however, PowerQuest, the original owner, was bought by Symantec some time ago and now I believe the Symantec is trying to incorporate Drive Image's capabilities into 'Ghost'. If anyone has any advice as to how I can get rid of all that other stuff in the iso file, except Drive Image, of course, and still use the application properly that would be great. However, I was mildly surprised at the number of other applications on the CD, all I wanted was the 'Drive Image 7'. When I got the iso file, it was labelled 'Drive Image 7' and I wanted to try out this software for backing up my HDD. The CD has a number of different bootable OS's and a variety of software for diagnosing/troubleshooting computer systems. I actually forgot about this post, otherwise I would have posted the link to the article right away for others to see/learn. If anyone wants to read it, I'll try to find it again. There is actually only one(1) copy of any type of file and the rest are pointers to that file instead of having the same file numerous times on the CD. I did actually find an article that explained what was happening to the data when you compress/optimize an image to be burned. Nic is correct as far as having multiple versions of OS's on the CD. Thanx for the advice/insight on the issue of. If not, then please llist the programs on the CD. It might help if you listed what is on the CD, but I figure I must be on the right track. The size will therefore be much larger and will not fit on a 'normal' CD. What you have done is extract multiple copies of the various files that only existed as a single copy in the image.

The problem you have is that once you have extracted the files, you don't have a similar tool to put them back in the same way. I've seen it several times with various software. I believe Microsoft has been known to use this format/technique when putting multiple versions of SQL Server on one CD, when under normal circumstances these wouldn't fit. If more than one application on that image file shares files with another, then rather than have two copies on the CD, it is possible (using special tools) to put just one file on the CD image and have the table of contents for each application point to the same physical file. I think you are talking about one of the special CDs that have more than one version of a particular application present.
