Assume that you have 1GB of free RAM (your internal computer memory) and you want to work on a picture that consumes 1.25GB of hard drive space. Elements needs to load all 1.25GB of the file into RAM. Therefore, an auxiliary source of RAM is needed for you to work on the image. Elements uses your hard drive. When a hard drive is used as an extension of RAM, this source is a scratch disk.

If you have more than one hard drive connected to your computer, you can instruct Elements to use all hard drives, and you can select the order of the hard drives that Elements uses for your extension of RAM. All disks and media sources appear in a list as 1, 2, 3, 4, and so on.

Warning: Don’t use USB 1.1 external hard drives or other drives that have connections slower than USB 2.0, Thunderbolt, or FireWire. Using slower drives slows Elements’ performance. USB 2.0 drives are being phased out and giving way to the newer, faster USB 3.0 drives.
