In macOS, the folder that has the .FPBF extension appended to it is labeled as just Burn Folder, but you might see it elsewhere referred to as a Finder Backup Burnable Archive file.
How to Open an FPBF File
FPBF files can be opened with Apple’s Finder. Some FPBF files might also open with Adobe Photoshop. If this works for you, then all Photoshop is doing is opening a Photoshop-compatible file, like an image, that’s stored within the FPBF file—you can’t use Photoshop to burn the files to a disc like the Burn Folder is intended for.
How to Burn Files on a Mac
To burn files to a disc on a Mac operating system, you can either use Finder’s File > New Burn Folder menu option or just right-click the desktop and select New Burn Folder. Either way, a new folder with the .FPBF extension will be created. macOS may even create the FPBF file automatically when a blank disc is inserted. At this point, you can drag and drop files and folders into the FPBF file that you want to have burned to the disc. Please understand that doing this doesn’t actually move or copy the files into the FPBF file. Instead, a shortcut to the original files are all that’s being created. While the files you drag into a Burn Folder are just aliases to the actual files, you need to make the distinction between files and folders as well as between your Burn Folder and your hard drive’s actual folders. For example, if you drag a folder that’s full of files into the Burn Folder, and then open said folder from within the Burn Folder, what you’re actually seeing inside at this point is the data that exists on the hard drive (since the folder is a simple shortcut), which means if you remove a file from that folder, it will be deleted from the folder on the hard drive as well. When you’re ready to burn the files and folders that the FPBF file is referencing, you can either right-click the Burn Folder and choose the Burn "" to Disc option or double-click the folder to open it and then choose the Burn button located at the top of the window.
How to Convert an FPBF File
There aren’t any file converters that can convert an FPBF file to a different format. The format is used for the specific purpose of gathering data that you want to burn to a disc; having this file in any other format would be useless. To be clear, the FPBF file is not an “image” file like other disc image files, so converting it to ISO or IMG or something else just doesn’t make sense, technically.
