Any reason not to install games to a seperate partition?

I know not all games work when installed to somewhere other than the default directory. Couldn't give you a list unfortunately.

i have it that way, 300gb of games. Also have multiple os installations(for testing different OS/troubleshooting mine and other's stuff), and haven´t reinstalled some games since i had xp. I don't think i had any issues, all the contrary, it is much more manageable this way.

I also keep another partition for apps and data, and the C: partition for the corresponding OS and the applications that actually need reinstalling (use mostly portable apps, huge time saver when moving between os/reinstalling).

I have a separate harddrive that is dedicated to Steam. I installed Steam and all my games to that and haven't had any problems. I've reinstalled Windows at least once and all my games were good to go. :)

If you have more than 100 gigs of games, it's always a good idea to have them installed to another drive. I can't imagine having to download all of my games all over again after a pave/nuke of my OS.

got separated hd (700 gb ) just for games..... all the save files are on documents (most of them) i just copy them into a external memory or someplace while making roots for example( C:Documents\Mygames\ this that or w.e folders they originally were at so i just copy paste after re-format

Yeah, what I do is put all my new games (high resource) on my main SSD, and old games (low resource) and games i'll rarely play on a separate drive.

Thanks I will be partitioning a new drive :) Any suggestions for the size? 100gb? idk
My C: drive is 500gb (450 usable)

A separate drive would be better. Noticeable increased performance/loading times too, at least for me.

Installing a game on a different partition in your hard drive is not a good idea. When windows create a new partition in your hard disk, it creates something similar to a divider with a virtual bridge, so that the two separate partitions remain separated. The OS partition will always be faster than the other because it takes less time to process data on the same partition. That's why when you move items within the same partition it does so instantly, as opposed to cutting and pasting the same 2 gb item into the other partition.

Having said that, if you want to put all your games into a different partition than your OS, it's better to get another Hard Drive dedicated for games. Transferring data between 2 HDD in the same system is faster than transferring between 2 partitions of the same HDD. Try it if you have the chance.

Personally, i haven't had any problem installing STEAM games in a different drive.
But, i would NOT suggest doing that with any you get from GOG.com.
about 1/2 of them won't work. Seems Gog's installer has a bug that doesn't change values
in the .ini files and the game doesn't know where to look for everything it needs. my 2cents

Never had an issue, have been doing this for years, much better when reinstalling windows from it being a douche unlike my lovely Linux drive which never messes up and I would marry if it was legal in my state.

Windows problems, Just like a man to do the organizing wrong.

I do it on my laptop. I also partition to dual boot linux.
I notice that you are worried about game saves, but you'd have the same worry if Steam was on the same drive as the saves/main so it's moot?

I install all on D, and only started to install on E when there is not enough space on D.

Well I have the following setup

60GB ssd as c:\ windows only.
2x250Gb drives on a RAID0 for steam.
Everything else on a third 250gb
then films and downloads on an 80gb
then a 1TB external for backup.

Benefits of this - I can reinstall windows and not worry about a single thing being lost.

the RAID0 on mechanical drives, simply the best way to obtain performance out of them and it shows up as 500gb. I'd strongly recommend RAID0 across two drives rather than a single drive for that performance gain. Only problem with RAID0 - If one of the two hdd's fails, it's dead and you lose the lot so the risk is double. But performance gain is massive.

With regards to older games, it's a bodge enough just to get them to work on windows 7, so If you are desperate to play older games, like the abandonware era games. Get VMware workstation and install XP on a VM and play your games in there. With that all you have to do is put the three VMware files on any hdd you want. Simple :)

I always installed my games on seperate partition, leaving the C: almost windows exclusive. Having backed up all the installation files, I tend to reinstall everything and saved the saved games from C: beforehand if I reformat. Not all games work without having to reinstall since some of its content went into registry, etc.
Yes, I'm doing it the hard way. There's always an easy way but I just don't mind.
