I have a 120gb SSD drive that has about 50gb left on it. I also have 600gb HDD drive. The SSD drive has my OS on it and is super fast when loading up windows. I have FSX on my HDD drive right now, and although I don't know what type of HDD drive it is, I do know that it has to be extremely slow considering that it is about 6 years old. I was thinking about putting my fsx on the SSD drive but was worried about it sucking up my SSD space. I'm sure the performance would be better on the SSD drive, but was hoping that there was some way to install FSX on the SSD, but putting other folders on the HDD, folders that are not in use much or something like that. Was curious if this was possible, and if so, how?One more quick question... When installing FSX, I have heard that it is best to install it in it's on directory, like C:\Microsoft Flight Simulator X, instead of going through program files and all that. Is this true or just a myth? Thanks again guys!

1) Yes, putting FSX on the SSD is fantastic. Highly recommended2) Yes installing it to a custom directory makes a lot of permissions/admin related problems go a way. You can do it either way, but its easier and less troublesome in its own directory.-George

I filled up a 120gb drive real fast with fsx and windows.

Place FSX program and "selected" addons" and scenery BGL on the SSD. If you are a typical long term user you may have as much "extra" stuff as I do - around 60gb. Lots of that can stay on the hard drive. Remember as you fly FSX is constantly loading scenery elements based upon your direction of flight. If you go all over the air space it is constantly grabbing stuff to satisfy your latest direction of the aircraft. A lot of FSX stays in memory so scenery BGLs tend to be the biggest beneficiary of FPS if on an SSD.

So did I. Now I have got a dedicated 128 Gb SSD for FSX which hopefully will suffice a bit longer but not forever. But I don't see how you could place some part of the FSX installation on a SSD and other parts on a another drive. When you install FSX and addons you are prompted for one installation path.

I have a 120GB SSD containing Windows 7 and FSX. I now boot up at 35 seconds compared to over 2 minutes with a mechanical drive. I currently have 31GB of free space remaining. I do, however, make sure when installing any other programs (Office, etc.) I put them on a mechanical drive (actually a partition of a mechanical drive) and not on the SSD. Exceptions are Firefox and a couple of utilities I use that I want to be fast.Any FSX addons I install go to my fastest mechanical drive (in my case it's a Seagate Barracuda but there are much faster drives) and they take care of themselves putting in the hooks to FSX during install. I can't think of any programs offhand that do not allow a choice of install location.As far as splitting up the FSX folders between SSD and mechanical, I can't say for sure that will work as I don't do it. But I think maybe some of the scenery folders (a very large chunk - my "scenery" folder is over 20GB alone) could be moved off but then wouldn't that be contrary to the purpose of using SSD in the first place? I mean, part of the speed boost is immediate access to loading new scenery files as you fly.BTW, I let FSX install with default parameters and have had zero issues with permissions and the like. (C:Program Files (x86)Microsoft GamesMicrosoft Flight Simulator X)YMMV

I do have quite a bit of scenery. Probably enough to overflow the rest of my SSD if I was to install all of FSX on my SSD.

This is extremely true. I want things to be smooth and flowing, as well as an FPS boost. And I believe putting FSX on an SSD would help with doing that.But my question still lies. is there any way to split up files/folders between hard drives but yet still be able to run FSX?
