Rebuilding the desktop file; what is it and why would I need to do it?
The Desktop file is an invisible file found in the main level of your hard drive. It is the file that keeps track of all the documents and applications that are on your hard drive. The file name is Desktop for versions of System 6 and earlier. System 7.0 and later versions use the invisible files named Desktop DB and Desktop DF. Occasionally your Desktop file may become too large or may be damaged. One symptom of a damaged Desktop file is the icons on your desktop appear as generic rather than custom icons. The Desktop file manages all icons on a particular hard drive or floppy disk. When you insert a new or customized icon, the Desktop file may not load it or may load a previous version of the icon. To have the special icon appear on the desktop, the Desktop file must be rebuilt to update the Desktop file and register the icon.
