Anyone know why this is?

I have this image of a cd and it's 674mb.

here the cd...

But if you select all the file on it is 1.13GB.

What's going on?
It burns to a normal cd.

Probably because when it's unzipped it's 1.13? maybe?

Explosive_Cornflake

It's not zipped though, it burns as is onto a 700mb disc, but if you select off the files on the burned disc, there 1.13 gb. No compression involved.
BTW i threw in an extra pic above.

I think I know whats going on. The image thinks it's 1.13 GB big, and when anything asks it (like windows), it will say it's 1.13GB big. However there is only 674 MB of data there. So if you tried to copy or move it, it might feck things up. Can you copy it OK?

I heard of a guy who manager to put a 1 GB file on a floppy using a method like this.

Copy's no problem. Suppose it might be some file misreporting the size, but this is before and after it has been burned. Hmmm.

has it happened with any other's?
or just that 1?

Might be some kind of copy protection?

but would copy protection give misreadings?

Explosive_Cornflake

Trust me when i say there is *no* copy protection on this cd .
Happens across many computers. All i have looked at it on anyway.

Da_cOmRaDe_MiKe

beats me... never seen something like it.. although i probably wouldnt have noticed..
but everything works fine right? i reckon thats the important thing...
your not loosing out on anything?

Superman

try and locate the file on the cd that is creating the size reading error, and investigate it.

Explosive_Cornflake

Everything works great. Hmm, i'll see what scanner.exe makes of it.
Not much else...


Actually handy little program. Not mine though

I have a disc like this too. Win2k Pro, Server & Advanced Server all crammed into one disc. If you make an image of it, the image file is less than 700MB, but if you copy and paste all the files and folders to the hard drive it comes to around 1.2GB. I believe it has something to do with common files between the 3 variants of Win2k being only recorded once in fact but somehow being referenced multiple times in the disc's table of contents resulting in the larger amount of data when you copy it to the hd because it copies these files 3 times. That's the only explanation i can offer at present, is it possible that your disc also has some jiggery pokery done with common files?

Edit: Just noticed in the pics of your original post that it is Office 2003 so I'd say the likelihood of mine and yours being similar situations is increased since they are both M$ discs.

I suppose there could be some overlapping somewhere.

When you do a search in windows it looks inside some compressed file types.

I take it you have parted with about €1,500 for the legit licenses for this disk. Remember M$ have only $50Bn in liquid assets, failure to keep supporting them could affect the quality of future software releases !

Office 2003 that I have comes on 5 discs.
Disc 1 is Access,Excel,Frontpage,Infopath,Outlook,Powerpoint & Word and is 400MB. Disc 2 is Publisher and is 198MB. Disc 3 is Visio and is 227MB. Disc 4 is Project and is 154MB. Disc 5 is OneNote and is 78.4MB. Total 1,057.4MB so I reckon they could do it alright it there were a lot of common files.
