EG
i have a cd ( it's storage limit is 700 mega ) but when i see the total files size of this cd ( the total file size was 3 giga )
how can i but files( 3 giga ) on cd (700 mega)?

when i copy the files to my HDD and try to copy the sam files to another cd, a message appear to say you can not because the files too larg size !!!
 
OK. are the files compressed on the origional CD? Using WinZip or similar?

well, the fact is that there is something wrong.
1) ur file could be damaged, so that instead of 300(or any other mb till 700) it says 3 Gb
2) Ur Pc might have some malware.
check out another file size.

 
dear Santei

when i copy the files from the cd to my HDD, read the same size ( 3 giga )
and
when i try to copy the sam files to another cd, a message appear " you can not copy because the files too larg size " !!!
that is means the size is true
 
If they are the same size in the CD and the HD, the the CD is not a CD but a DVD. Look at it closely, it must be a data DVD.

Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.
 
Why all of here not believe me
T H E C D I S N O R M A L O N E N O T D V D
I have not a dvd drive
 
kind of, miracle :/
please if u find out the reason please post about it.
 
when you right click/properties in explorer, what filesystem is reported (cdfs?)
 
Oooh! Oooh1 I know the answer to this one! :-D

I ran into this once before on a CD that had support for multiple OS's. It was a regular 640MB CD, but when I copied the files to my HD, I got something like 2.5 gigs!

Here's what happened.

Several of the files were "common" to all of the operating systems (for example, DLL's, and so forth)... but...

In the DIRECTORY STRUCTURE, there were MULTIPLE ENTRIES in separate folders that pointed to the SAME FILES.

SO.... for example.....

In d:\install\Win9x was a file called foo.dll which pointed to the file foo.dll
... and in
d:\install\Win2K was a file called foo.dll that pointed to the SAME physical file on the disk.

Ergo.... Windows, when copying the files, would copy the same file TWICE. It only physically appeared once on the CDRom, but there were multiple directory entries, in different folders, pointing to the same file.

The only way to copy the CD was with an image copy; you couldn't do a file copy, because it wouldn't fit. :)

Mystery solved.

wow, sounds like turth.
suzytek now u need some image/backup software to copy that file, don't u?
 
WOW , thank you so much gbaughma

you are right Santei, now i need this software can you tel me where?
but gbaughma , can i do that with a movie for example or some other files like word, is it possible.
have a nice day every day.
 
Well, the issue is that there's not *really* that much information on the CD; the CD can hold 700MB. Now, that can be 700MB of *compressed* information; for example, a regular CD can hold about 70 minutes of uncompressed music, but it can hold roughly 700 minutes of MP3 compressed music.

Uncompressed video is HUGE... but if you compress it with, for example, DIVX, then it will be considerably smaller and thus you can fit a "longer" video, but the CD is still physically limited to 700MB.

When you copy the files from that CD, since it has multiple file entries pointing to the same files, your computer is copying the file multiple times; that is why you're seeing so much data.

As far as actually copying the CD is concerned, just about any CD mastering software (Roxio, NERO, CloneCD, etc) will make an image of the CD, and write the image back to a blank. But dragging/dropping the files into a temporary directory then burning them back again won't work; because when you drag/drop them, you're making multiple copies (one for each directory entry).

It's like this:

Doc1.doc, doc2.doc and doc3.doc all point to the same PHYSICAL file, which is 1K in size.

No matter which one you open, you're opening the same physical file.

HOWEVER, if you copy them, since there are three file entries, you will get three *identical* files, with 3 different names, totalling 3K in size. On the CD, it's not 3K, it's only 1K, but because there are three different directory entries pointing to the same physical file, windows will make 3 copies of the same file if you attempt to copy it elsewhere.

It's a little bit of smoke and mirrors to make the computer *think* that there are 3 separate files, when in fact, it's just three INDEXES to the same physical file.

Kind of like 3 card catalogue entries, but they all reference the same book.

You are trying to copy a game? Dont ask me how I know. They put a dummy file in there thats like 200k but the system and CD Burn software sees it as far bigger than the CD can hold. This is a copyright protection tactic.
