How to move application data to a RAM disk

Moving browser cache and Windows temporary files

Web browser cache and Windows TEMP/TMP files can be moved to a RAM disk as described in this article

Moving application data

For moving application data, e.g. temporary files or log files, to a RAM disk, you can use symbolic links.

Symbolic links (or symlinks) are essentially system shortcuts, allowing you to redirect one file or folder to another. They appear like normal files and folders in the system, but in reality they are links pointing to a file or folder in a different location.

Some applications may have hard-set requirements as to where their data and temporary files should be stored. If you want to move that data to a RAM disk, you will need to create a redirect.

For example, you have a program that demands that its temporary data must be stored in C:\SomeApp, but you would like to move it to your RAM disk at R:\SomeApp. To do that, move the SomeApp folder from drive C: to drive R:. Then open the Command Prompt as Administrator and type:

mklink /D C:\SomeApp R:\SomeApp

If the paths contain spaces, you may need to enclose them in quotation marks:

mklink /D "C:\Some App" "R:\Some App"

Please note that some applications may not work correctly if they are redirected to another location. Therefore, it is important to test the new arrangement before using it for important work.
