Compressed files

[millman12345]

Ok this is a strange question... Normally I would just check and see myself, but I can't attempt right now as my PS2 isn't modded yet.

Ok so here it goes... If I create an ISO of my ps2 game (or any disk for that matter... I guess this is an ISO question in general) the normal, correct way, so that it was a 1:1 copy of the original disk... but used the NTFS "Compress contents to save disk space" option on the actual ISO file on my hard disk.. would it cause a problem when burnt to CD/DVD???

E.G.
1. Rip disk to my hard drive in ISO format
2. Use the Windows XP "Compress contents to save disk space" option on said iso to save space....
3. Burn said iso onto recordable media using prefered method (Nero for me)

Would this cause any problems with the actual burnt media??? Or would it burn the ISO's contents onto the media normally???

I know that this option doesn't seem to affect the USE of any files on my computer, but I'm not sure what (if any) changes this would make after burnt to the recordable media...

Any answers/ideas??

This isn't a HUGE problem, considering that even if it does effect the burning process, i could always enable compression on the files just for storage purposes, but then disable the compression before burning.... just curious, any help is appreciated... Thank you ahead of time.

Windows compression is available on the NTFS file system only, which is available on hard disks only. It is NOT available on the ISO9660 (+Joliet and Rock Ridge) and UDF file systems that are present on CD's/DVD's.

I fully well understand that... my question is, when i am burning the iso to a cd/dvd, will nero burn it the way it is originally meant to be burnt, or will the compression disrupt the burning process. I know that compression is only available on the NTFS fily system.... thanks anyway for the attempt.

Windows compression is so called "transparent": no software will ever see that the file is actually compressed. (Except for low level software but let's not get into this.) Burn it onto CD/DVD and it will get there uncompressed. Even if you could put there compressed, Windows wouldn't care about it and you'd see it compressed and, therefore, unusable.

(Perhaps, there's a CD/DVD file system standard that supports transparently compressed file but those are definitely not ones made my M$. UDF, maybe; Higher versions, not supported by Windowses yet?)
