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?

How did I guess :P

Sorry dude but I didn't finally understand what you try to say...
I always thought that files on DVD with 4.7 gb are 4.7 gb on your harddrive, too...

[kosmiq]

hmmm ok... Have you ever experienced dummy files as protection on games?
Like commandos, there are 3 files (I think) that claims to be 800mb on the CD on top of that is the actual game files. How would that fit on a CD? Answer is it doesn't. The files actually are not 800mb but shows themselves as that because they have an attribute that says so.

The same is on the Windows XP 11in1 DVD. Because the CAB-files are shared between the different windows versions they only need to really exist in one folder. But because of file checking and probably also size check (?) there needs to be dummy files that shows up at the correct size but are not that big when written onto disc. Most probably the filesystem is fooled into thinking that the files are bigger then they really are. But when the install is running it reads from the folder with the correct .cab files.

This release is ISO because of the special filesystem required.

I sure hope the above won't give me any troubles now, it was taken from the nfo of 11in1 XP. Note, I do NOT have this DVD I simply found the nfo somewhere, not gonna tell you where and how.
That little qoute tells me that the filesystems is most likely fooled.

Hope you understand now...

Okay, I understand... mostly. I get what you mean with the dummy files. So now the question stands, is there any way to edit the ISO one file at a time? With ISOMagic, the whole ISO has to be rebuilt even when editing something as small as a text document, then it's saved to a much larger file...

Unfortunately your talking warez, and its not allowed here :P
