Real World Photoshop CS5 for Photographers: Virtual Memory | Virtual Memory This excerpt from Real World Adobe Photoshop CS5 for Photographers shows you how to fool your computer into thinking it has more RAM than it really does. Virtual memory is a programming trick that fools the computer into thinking it has more RAM than it really does. It works by reserving a specially marked amount of space on your hard drive that gets treated as RAM. The real, physical RAM is then used as a cache for the virtual memory stored on the disk. Operating systems create one or more virtual memory swap files on your hard disk that serve as virtual memory to let multiple applications grab RAM as needed. The Photoshop Scratch File and the Operating System Swap File. In Mac OS X, the procedure for pointing the swap file at a drive other than the startup disk is way more complex, so much so that it's crazy to try to move it when it's so much easier to move the Photoshop scratch disk setting instead (see "Scratch Disk Space" later in this chapter). Scratch Disk Space. RAID.
