The FXB file contains a bank, or group, of presets that can be loaded into a VST plugin. Single preset files are saved as .FXP (FX Preset) files. How to Open an FXB File FXB files are plugin-specific, so an FXB file that's made for one plugin will work in that plugin only, and a different one will open in its own plugin. You should know which plugin the preset is for before deciding how to open it. Steinberg Cubase is one program that supports FXB files. The software isn't free but there is a 30-day trial you can download for Windows and Mac. Another program from Steinberg, called HALion, can open FXB files as well. Since Cubase v4.0, VST Preset files (.VSTPRESET) have replaced the FXB and FXP formats, but you can still open them through the Earlier VST Plug-ins folder. Choose the SoundFrame button and then select FXB/FXP to load the FXB or FXP file. Ableton Live, Cantabile Lite, Acoustica Mixcraft, and IrfanView can open FXB files, too. If your file is definitely an FXB file, but none of the applications mentioned above will open it, then it's very likely it's not an FX Bank file. Try opening the file with a free text editor to inspect the header of the text document. You may find some useful information about the format there. In a sort of opposite problem, you may find that you have more than one program installed that opens FXB files, but the one that's configured to open them by default isn't the one you want to use. Fortunately, this is easy to change—see our How to Change File Associations in Windows tutorial for help doing that. How to Convert an FXB File Most files can be converted to a new format using a free file converter, but FXB files are an exception. We, at least, haven't found a dedicated converter tool of any kind that supports these files. However, something you can try, which we don't have much information on, is Wusik VM. It should be able to extract preset files out of an FX Bank file, essentially converting FXB to FXP. You can also use Steinberg Cubase to convert an FXB file to the newer VSTPRESET format using the Convert Program List to VST Presets option. The new file will be saved in the program's VST 3 Preset folder. It's likely that the other programs listed above also have some way to save the FXB file to a new format, maybe even something different than .VSTPRESET. Just open the file in that program and, if it's supported, choose whatever Export or Save as option that's hopefully available (usually found in the File menu) to save the FXB file some other file format. Still Can't Open the File? The most likely reason for why you can't open an FXB file at this point, after trying the FXB openers above, is that you don't really have an FXB file. What's probably happening is that you're simply misreading the file extension and mixing it up with one that looks similar. For example, the Autodesk FBX Interchange format uses the .FBX file extension which looks an awful lot like FXB but they actually aren't related and cannot open with the same programs. If you really have an FBX file, you can't use the programs mentioned on this page to open or edit it but should instead use an Autodesk program. Some other file extensions that you might confuse for an FXB file could include FXG (Flash XML Graphics or FX Graph), EFX, XBM, and FOB.
