GiliSoft RAMDisk appears like a physical hard disk to the operating system and programs. You choose its size (depending on the amount of RAM in your system), drive letter, and file system. You can copy, move and delete files on it. Like a physical disk, a RAM disk can also be shared so as to be accessed by other computers on a network! The RAM disk bypasses the system hard drive, which is the slowest part of a computer. Freeing your data storage and retrieval from this mechanical disk gives your system an immediate boost.
