A storage place on your hard disk (or in any other storage medium, such as a Zip drive or a CD-ROM), in which disk files are kept. A folder is designated by a backslash symbol (\) followed by the name of the folder. The folder in which Diet Power 4.4 is normally installed, for example, is \Diet Power 4.4. A file named, if stored in the \Diet Power 4.4 folder, would be designated as \Diet Power 4.4\ (In DOS and Windows 3.1, folders were called "directories." Some people use the terms interchangeably.)
