probably copies split files to the internal and merge them there then shadow copies the large file to where it needs to be on the mounted drive.
If I already have a backup with a big file on an ntfs hdd, is there a pc utility which can produce split files that Iris recognizes or do I have to transfer it back to the internal hdd and let Iris do the copying and splitting to the external FAT32 hdd?
I've no idea if that assumption is correct mouseclicker it was just a guess on how it works.
But first of all you can't play any games from an NTFS drive so they're going to need to be moved for a start, opensplit (pretty sure that's what it is called) can split large files for you so they can be stored on fat32 drives. After you have the split files on a fat32 hdd iris manager will do its thing from there, but I haven't looked at the source as to how it exactly does that.
ok please help.. i know I'm a noob but since i don't understand this technology talk... does when i back up my game with this software will i be able to run the game from the xmb or do i have to do some other stuff? plz help.
You have to go into whatever backup manager you use and pick the game from there. Some games will let you launch them from the backup manager and/or without a game disc in the system (it doesn't matter what game disc you use). But in a lot of cases (at least in my experience) this does not work.
So you may have to choose not to "direct boot" which will take you back to the XMB. If done correctly, the game you chose in the manager will now show up instead of the game that is actually in the system. I use Multiman as my backup manager, so there may be some slight differences to what I say, and what you must do. But for them most part I believe that is how a lot of the managers work.
It is also worth stating that some games will not work depending on if you are trying to run them from the PS3's HDD or an external. It all may not make sense at first, but just make sure you take time and read the instructions for whatever manager(s) you use.
