Is it not the case of installing games into another folder on another drive and avoiding the 'C' drive default installation altogether? I believe this has always been a standard operation for Win7 and 10 users as it increases C drive capacity and avoids the pesky windows UAC (user account control) having access to games and other programmes that it has an effect on.
But then you don't get the benefit of booting games super quick on the SSD? IL2 has to be installed in a separate folder away from Program Files, but the drive is up to you isn't it?
Unless i'm totally misunderstanding you Uncle Sidly! (Entirely possible).
No, no misunderstanding favourite nephew, out of Program files is the way to go. I have 4 drives on my pooter. All my games except IL2 are on one WD Raptor, the OS is standalone on it's own WD Raptor, I have a backup ssd and IL2 is on another WD drive along with all the associated programmes. I don't know about faster bootup times for games as my ssd is the Backup drive due to the fact that that drive needed replacing due to age and I haven't got around to swapping stuff over.
