[Solved] Recommend a good compression tool?

I'm trying to compress a .ISO file of the Korean TV Show "My Girlfriend is a Nine-tailed Fox" for my sister and her flash disk (although has 5.44 GB of free space out of 8 GB) seems to not want to take the bulk of a full 4.53 GB ISO. So which tool can probably reduce it to at least half or less? If that's too much to ask, then something that would slice a GB or two from the ISO?

ISO files cant be compress since they are already compressed, so IMO don't waste your time finding any way doing that .

Apparently MagicISO does compress .iso's (i've not tested myself.)

Maybe worth giving a go ?.

Please note, i've grabbed this link and it's got the main setup and code in text file, I've NOT installed however, so I cannot comment of the viability of it compressing an ISO.

I have compressed iso file of oxford advanced learner dictionary v8 resulting in 200 mb compression in size by using 7-zip ultra compression mode

I believe demoneye is correct. That being said, sometimes the way the ISO created takes more space than it should. It's difficult to explain. In most cases, trying to re-compress and ISO is a waste of time. Tools like MagicISO *might* help but don't get your hopes up especially since you're dealing with media files.

Another option is to re-encode the files but that's a whole different ball game.

U dont need compression tool, u need dvd authoring tool like nero video, ashampoo or convertx2dvd ,or any other software that u prefer, change bitrate of audio or video, or change resolution, or compress to advanced format like mpeg4

correct , he can downgrade his resolution or frame rate and shrink it much more , but like u said its another ball game :)

What you guys seems to be forgetting (Or dont know) is that his flash disk is likely fat32 so he wont be able to put 4GB+ files on the disk unless he formats to ntfs.

@ insanedown

All you need to do is format disk as ntfs or split the ISO into 2 or more segments using something like WinRAR and its volumes setting, No compression is needed you can just use the "store" setting.

UltraIso can create isz-Format, that's an own compressed image format. How high the compression rate will be at the end, depends on the data the original image contained.

-Delete unnecessary video frames (like ads) but that is very time consuming

-Downsample the TV-Show (or re-encode with higher compressed video containers)

-Re-create the iso and luckily enough you can get the 1 DVD-5 result

Options so far:

  1. Convert your drive to NTFS. -> Most recommended by me.
  2. Compress your ISO with image software's own compression method, but, can that format be read by the opposite person's device?
  3. Compress with WinRAR or 7-Zip.
  4. Extract the ISO and convert the things inside to a lesser bitrate (or use other format with lesser bitrate). ---> Second most recommended by me.

Seeing that I can't, I was opting for another solution which was told here. That solution was to re-encode the videos. My problem with that is, even though it was technically re-copied it still won't rip for some reason. There are some episodes that doesn't seem to want to be ripped. The ISO works well though and the episodes are all nice and intact. The reason why I had to do this is because the scratched a hell lot and my sister wanted me to salvage the data which I was (in a sense) able to do.

Dude, You have ...ZERO... need to compress, rip or convert it etc so do not listen to any of the comments that recommend converting, especially teh one that mentions ratDVD (The quality is absolutely dreadful). All you need to do is pack it into a split volume archive and this will allow you to store it on the fat32 flash drive. If you need to load teh ISO from the flash drive then just simply backup contents, format it to ntfs and then restore files back and the full ISO should also copy to it.

I compressed it with WinRar and decreased a good 1GB out of the ISO and I was able to punch it in the Fat32 USB.

wait, wait, so after all this and you creating a topic about good copression software you hadn't even bothered to try WinRAR? :s

What a complete a utter waste of time this topic was.
