Creating compress cd or dvd

Hi guyz,

Thanx for dropping by and sparing some time to look at my question.
By ‘more’ I do not mean a couple of MB to overburn or 90 seconds of lead out. What I mean is how to burn 1.2GB worth of data onto an ordinary 700MB/80 minutes capacity cd-r.

I have downloaded an .iso file b4. I mount that file by using Alcohol. Then I open up ‘My Computer’ and right click on my virtual drive to access its properties page. The content is taking up less than 700MB. But when I went into my virtual drive and select all files and folders, the property page reported a 1.4GB worth of data.
Another instance of this case, is Microsoft Office 2003 installation cd. That cd houses 5 of Microsoft’s finest suite of softwares which take up about 1.3GB of space.
Knoppix Live CD is by far the most amazing case I’ve ever seen by whopping down a 2GB of data into a single 700MB cd. Maybe Knoppix is a bit too much to ask as it is compressed in a different operating system. What about Microsoft Office 2003? How they do that? I hope I can find some answers here.

I have posted this question in countless forums before this. Some suggested that I use a dvd-r by saying that it is cheap and have a higher capacity to further support their point. I realized the existence of dvd some time ago and I know it is getting dirt cheap. Well, it’s just that I DO NOT want to use a dvd-r, period. In my country, dvd mediums are getting very cheap, however not many people can afford a dvd-rom or even bother to buy one as a cd-rom is sufficient for data distribution.

Some proposed to compress the data into rar or zip files or with whatever archiving tools out there. But that does not provide a transparent compression as I need to uncompress the file onto my own harddrive when I need to use it in the future. I need to wait for sometime to uncompress a 1.5GB of data. Btw I doubt that rar file can compress 1.5GB of data into 700MB. Well, if you are trying to suggest that I compress the files onto a cd-r together with a decompressor and this decompressor will fire up and run in the background without me realizing it and uncompress those data on-the-fly as I read it, then it’s acceptable. But how? Please tell me how to do it.

Some even asked me to split my files up and burn into 2 or more cd-r. Perhaps they didn’t read the title well. Duh, if that is the answer I am expecting, I wouldn’t be wasting my time posting this question.

Some said that a compression technology is behind this but didn’t mention what it is. Well, as if I don’t know that the world is round and that my mom is a woman. I really hope that I am able to find some ‘quality’ answers here to my question.

If you can help me, can you provide a comprehensive set of instructions of what I need to do and what software or tools involved as I am new to this compression thingy.

Thanking you guyz in advance.

here’s a sample of the cd i’d mentioned…

The CD doesn’t use compression - it uses a technique where the same files appear in two or more folders, but the content of those same files are only stored once on the disc.

This is very useful when making CDs or DVDs where some files appear more than once, e.g. because multiple language versions use some of the same files.

It doesn’t let you put more data on the disc than the normal capacity of the disc, however.

owh… ok thanks buddy…
so do you know to do this by using software or manually…?

UltraISO (Shareware) and ImgBurn (Freeware) can create and burn such discs if you use the right options. There are probably other tools also capable of using this technique.

In UltraISO you should use the [I]Optimize[/I] option on the File System tab in Properties.

In ImgBurn you should use the [I]Optimise Duplicate Files[/I] option on the Build tab in Settings.
