I can's explain this...

And I wasn't sure of where to post it. I'm looking for a little help.

I can't figure out what the hell is going on. I have a certain DVD with files on it. It's a 4.7GB data DVD. I can create an ISO image of the DVD on my hard drive and it comes to 4.36GB. I can mount it in a virtual drive and burn it to another DVD, both work flawlessly. However, when I extract the files from the ISO file or copy them from a burned DVD, the files come to over 13GB on my hard drive. How is this possible? Windows shows the DVD as being 4.36GB, but when I highlight the files and go to their properties, it says there are over 13GB!

This makes it very hard to edit the DVD, which is what I'd like to do. WTH is going on here? Is there something just freaking out, or is there a program I can use to copy the raw files to the HD without the extra baggage (that shouldn't.... physically be able to be there...) I'm at a loss. Thanks for any help, and if this needs to be moved, by all means.

I don't know what is going on with your DVDs but try making an image of the DVD and edit the image itself with a program just like UltraISO which edits CD/DVD iamges of a lot of programs (not all but many of them).
Then burn the image ....
Give it a try !

Thanks for the quick reply! Yeah, I tried that... I editied about 6 text documents on the dvd image and saved it, and it saved to 13GB...

edit- I used magicISO to do the editing, WinISO can't open files that large.

Im guessing this is the 11in1 Windows XP DVD we are talking about here?

If my post doesn't get removed for mention of it, and you have an answer to my question, then yes.

this occurs because all XP versions shares the same .cab files (well most of them atleast). They are crosslinked all over the place, this means that when you extract it, it will get each cab file and put it with the rest of that windows xp files.
Hope you understood what I meant, I am not sure how it works but that is how it is done...

remove post if you feel it is necessary...

Edit: To clarify a bit,
Windows XP Pro and Windows XP Home uses almost the same cab-files, they simply use different files from it. Of course and Driver.cab will be the same so that will be on that can be linked to from another positition.
I also think that many of the cab-files might be some kind of dummies. So that those dummies works just like on some mini-images. Like BF2 mini-image from BleH, mount it and all files has the "right" size but are not usable.
So if Windows XP Home has the same driver.cab as Pro, one of them will simply use the one from another location.
Cr*p, this didn't get any better... Someone that can understand it and write it out so that someone can understand?
