I have FSX Acceleration with UTX/GEX/REX all installed on my C drive. Would it benefit to place them on the other blank drive? If so would it mean doing a re-install of everything?

2 x Hot Swap Drives - You mean for security reasons or to have more space?If You answer is for more space, do a complete reinstall. Put OS and all programs on one hard drive and FSX and all FSX's add-ons on the other one.

I could use more space but that's not the main issue. If I make the move it would be for performance of FSX.

I do not believe if it would be possible to copy the whole FSX folder to new drive. FSX lays in plenty of places on Your disk - ProgramData, AppData, Documents, Registry... Many of them!I do encourage You to do Format C: and put OS and FSX on separate drives. You will gain a little performance (especially with textures loading time). But do not expect that Your FPS will double.

I just simply copied and pasted the entire FSX folder from my C: drive to a formatted D: drive over 2 years ago....Went into the FSX folder on D: and created an icon of the FSX.EXE on my desktop..You are still running FSX from the os on C: drive......No problems...Lou

For slightly better performance, you can install the texture programs (REX, GEX) and some others (ASA if you're using it, any third-party AI programs) on the C drive with the OS. FSX doesn't call them often, so performance won't be hurt if they're located elsewhere and you gain a bit since the FSX installation is smaller and more efficient. UTX insists on being installed in the FSX folder, and so do some other add-ons (for example, the ORBX FTX sceneries). Any add-ons that are called frequently (aircraft, acenery) need to be on the FSX drive.Once you're done with the installations, don't forget to defragment - the Complete/Name option on O&O v.11 works well.For more detail, search out Nick Needham's FSX tuning guides here and on Simviation.Hope this helps.Alan

Thanks for the info. Currently I have everything on my "C" drive. I'm thinking about moving FSX/REX/UTX/GEX over to my "E" drive simply because it is empty. I would imagine a slight if any noticeable performance. Really wondering if it's worth all the trouble to make that move.

Plus, it will be easier to defrag, clean both disk, when are not used at maximum capacity.Please do a backup of Your system before moving the files

Probably worth the effort in terms of performance gains - and also for maintenance, as BartEnder points out.But think about moving only FSX and UTX, and leaving REX and GEX on the C Drive.FSX is happiest in a smaller installation - makes for easier, faster file access as well as more efficient defragmentation. It won't show in frames but it'll show in the quality of your textures, as well as their load times.Alan

thanks for the reply. So if i'm understanding correct. I don't need to reinstall FSX to the empty drive? I can just copy it over along with UTX while leaveing GEX and REX on the C drive?
