So originally i was gonna go with CSO´s but i read that Gzip was supposedly gonna save much more space. So now i have to questions Nr1- my test game 007 - Agent Under Fire was 1.592.096=orginale ISO 1.412.947=CSO 1.364.982=Gzip with ultra compression done with 7zip. That doesn't seem like a significant change especially the Gzip. Am i doing something wrong?, wrong settings,wrong program?, Secondly if going with gzip can anyone explain how to batch convert multiples files so it could run over night. Instalasi pemadam kebakaran. I had read that it wasn't a huge jump personally. You will still also have to decompress these files when you want to play them and since they're compressed on Ultra it will take quite a while to boot the game depending on where they are located.
CSO's don't need to be decompressed. CSOing can break a game though, I've found only 2 game so far that don't work well like this. As far as Batch compression or if you are doing it right, I wouldn't imagine anything past default Ultra would be needed and I don't know about Batch compression. It's also worth noting that some games may give you a better savings in space than others, it just depends on the game. I have written a script for Gzip batch conversion, which may be useful for someone. File Structure (you can of course edit the script to match your own file structure):.
All ISOs must be in seperate subfolders (only one ISO per subfolder). The gz file will get the name from the folder name.

Examples:. 'God of War II (USA) God of War II (USA).iso' - 'God of War II (USA) God of War II (USA).gz'. 'God of War II (USA) image.iso' - 'God of War II (USA) God of War II (USA).gz' Usage:. Put gz.bat and 7z.exe (from 7-zip) in the folder where you have your ISOs in subfolders.

Run gz.bat Comments:. The script will delete the original ISOs. You can remove '-sdel' to keep the ISOs. If you want to have the highest compression level, change '-mx7' to '-mx9'. (compression level 9 compared to level 7 seems to make very little difference on file size).
If you add new ISOs, you can just run the script again (if original ISOs is deleted with '-sdel') Edited December 3, 2016 by Norfair.

The 7z source files will be deleted Description: The script batch converts ISO files from 7z to gz compression. There must be one ISO file inside each 7z file. The ISO file must have the same file name as the 7z file (excluding file extension). The 7z and the ISO will be deleted in the process. The script should quit if there is something wrong when unpacking the 7z.
Usage:. Put 7ztogz.bat and 7z.exe (from 7-zip) in the folder where you have your 7z files (no subfolders). Run 7ztogz.bat Edited March 17 by Norfair.
I have been trying to compress some of my PS2 ISO's to save some space on my HDD, but I have been experiencing troubles with some of the ISO's. The smaller ones were compressed with no problems, but recently I tried several times to compress Devil May Cry III ISO (3.775.136 KB) and its respective.mds file (5 KB) using 7zip, but it just takes forever. For every second it spends in the process of compressing, the remaining time goes up 2 minutes. When I tried to leave it overnight, for about 8 or 9 hours, the process was stuck at about 30% and with 247 hours or so remaining. Similar issues occur with other ISO's.
Is there a specific setting that I need to adjust on 7zip, or maybe a different compressing tool that would work better? Give these 7-Zip settings a go My PC's barely what I need for emulation of PS2 anyway but compression is fine, I'll show my specs Once I managed to compress GTA - SA within 10-15 mins on a high compression setting, I'll give it as an example Ultra takes up too much RAM on LZMA2; my PC can do it but it drastically slows down my PC for ages since my RAM is only 4GB (required is about 2GB) EDIT: Give WinRAR a go as well, sometimes 7-Zip goes weird so I use WinRAR instead and the.part1.rar and the.part2.rar is pretty good Last edited by ndsplayer19576; 12th-March-2013 at 22:40. Thank you for your help, ndsplayer, but I tried these settings and the same problem occured.
But maybe that's because my PC sucks so bad. The only difference I got was that the maximum number of CPU threads I could set was 2 (after the dash on the right of this setting, where your image displays '/4', mine shows '/2').Thats my thread count; I have 2 cores, 4 threads Can you give your PC specs anyways?
Just to make sure and while you're there give a lower compression setting a go Another problem it could be is to do with the algorithm of the 7z, in this case give LZMA a go EDIT: I'm assuming you've given the algorithms a go already, try doing a zip file (or rar with WinRAR) EDIT 2: Sorry for asking a lot, but could you give me the settings of the first time you compressed the ISO?
