RAM Disk for Temp files

Hello All,
I'm trying to create a RAM disk as the place for my Windows Temp files, but I'm clearly doing something wrong.
I have created a RAM disk R:\ of 4 GB and have told the software to create this disk at bootup, and to create a folder called Temp on the R:\ drive. This it is successfully doing, but the folder itself is empty. If someone could explain what I'm doing wrong I'd appreciate it.

What do you expect to find in this folder?

If you want to place Windows temporary files in it, you need to change the Windows %TMP% and %TEMP% variables to point to that folder. The easiest way to do it is to choose Tools - Set Windows TEMP folder from the RAM Disk's main menu. Then, after a while, you'll see temporary files in it.

@Andrew: I'm still confused. When I press the 'Set Windows Temp Folder' button in the Tools Menu, I get a pop-up box with two identical lines pre-filled in with the following: "%USERPROFILE%\AppData\Local\Temp". Are you saying I should change that line or is that the line as its supposed to be? I guess I'm expecting some line of code similar to a DOS-style "Set Temp=R:\Temp" - or is that the effect of the aforementioned button? Some specific instructions would be very much appreciated.

Those lines are the default Windows location for temporary files. You can change them to the newly created RAM disk, something like R:\Temp.

Don't write anything like Set Temp=R:\Temp, just put in R:\Temp or whatever disk letter and folder name you chose, but make sure they exist. Windows and applications may throw strange errors if they cannot find a valid temporary folder.

@Andrew: And which file does the R:\Temp line of code go - autoexec.bat; system.ini; win.ini; or...? (I still don't understand why the Set command isn't the way to go!).

Many thanks for your assistance.

It goes to the registry: HKEY_CURRENT_USER\Environment

The set command isn't a way to go because its effect is not persistent (good until reboot).

If you want another way of doing it, here it is.

@Andrew: Thank you very much, both the location and the tutorial that it contains are exactly what I've been looking for. I'm confident that this will give me the information that I need.

UPDATE: That tutorial was exactly what I was looking for - how to change the environmental variables under Windows (my SET command). All temp files are now being written to R (RAMDisk) \TEMP. That'll speed up things. Thanks again.
