Wow. You're really not all that intelligent, are ya?

There is no image that is 5.5 GIGABYTES. It is completely impossible, it simply doesn't exist.

.iso is a filetype for a ROM. You're not asking how to compress an image, you are asking how to compress a rom.

Still, you don't help him

What you can do is to split the ISO and compress each part seperately or compress it over and over again, although I'm not sure this is effective.

They are called iso images, wise guy.

When you compress such large files you could split the archive into several parts. Right click the file -> WinRar -> Add to archive. In the dialog, change Split to volumes to something fitting, depending on what you need.

compress it over and over again, although I'm not sure this is effective.

Tried that on an executable, it did excactly nothing.

.iso is not a filetype for an emulator, an .iso is the image on the backside (the side that contains the data) CD/DVD disk, and people generally obtain them by pirating things, such as games. Hm, funny, this .iso wouldn't happen to be for Fallout 3, would it?

For one, you can't compress an .iso, that's kind of why they're put on disks, because they're so large and will quickly use up your HDD space...

Deathcom3s... suprissingly it isnt fallout 3
and why would you think that... its oblivion... and i legaly own these games... for those of you who think im a pirate...

You'll need a dual layer DVD if you want to burn it. There's no other way. Watch out though, some older DVD drives can't read DL DVD's.

About compressing, you can compress it with 7zip if you can properly configure it, but it will be useless then, since you can't compress a DVD image while keeping it in the same file format (.iso, .nrg, .mdf/.mds, etc)

 

[Deathcom3s]

No offense, but i don't believe you... why do you have an .iso of a game when you could just get a no-cd crack which, more or less, verifies that you own the game, but you just don't like using the disk?

 

[Draknyte1]

cause no-cd cracks can make the game look bad ingame if not done properly and .iso image if cracked properly make the game run seamless like the original...

alchohol 120% can do this with its securom new reading features...
but normally this .iso is larger than its original size... but when i copied oblivion i did not use the Securom new reading feature...

 

[Kwaliti]

Just Google for a fixed image of Fallout 3. They can't be bigger than 100mb or so.

You can compress ISOs, Generally however the efficency is low (10% only).

Use zip for the ability to decompress on the fly parts of it.
If you want optimum compression for shipping use 7z, its algerthicmithic compression insures optimum compression however the whole thing must be decompressed before any part of it can be read (I do not need to explain what this means hopefully).

Like I said though, generally the compressions is minimal and in the 10% bracket as the data on the disk is compressed.

5.5 gigs does not sound like a game, they are generally in the 6GB+ range nowdays (dual layer DVD).

 

[Reaper2008]

Yup. Best get a fixed image, or burn it to a DVD 9 (dual layer).
