An FPBF file is a Mac OS X burn folder that contains files or aliases of files to be burned as a data CD or DVD. It is used for storing data that will be burned to one or more discs. FPBF files may be created starting with Mac OS X 10.4 or later and typically appears on the desktop.

To create a burn folder in Mac OS X, simply right-click on the desktop and select "New Burn Folder" from the contextual menu. You can also select "New Burn Folder" from the Finder File menu. Once the burn folder has been created, you can drag files and folders to it. The total size of the folder will appear at the bottom of the window. When you are ready to burn the contents of the folder to a disc, insert a CD or DVD and click the Burn button near the upper-right corner of the window. NOTE: Apple computers no longer include a DVD disc drive. Therefore, FPBF files are less commonly used than with previous computer models that included a disc drive.
