Any free or free virtual in-memory drive? I am developing an plug-set for a number program and I have to comminute by using it with temporary files within the disk, when the temporary files are saved within an in-memory virtual drive the performance could be elevated significantly.

Hints for applying an in-memory virtual drive in Delphi can also be appreciated.

There is a free edition of VSuite Ramdisk that could suit your needs.

Check this one, it's with different sample RAMDisk driver from MSFT, and seems to become configurable with a few registry tweaks.
