I’ve just recently noticed in several FinalBuilder projects have a file extension of \*.FBZ4 and others have \*.FBP4.  
  
What are the differences and how could I have saved them in (2) different extensions?  
  
Thanks,

Chad,  
  
_.fbp4 - project file format (xml)_  
.fbz4 - zipped project  
  
If you do a “Save As…” you can choose which format to save in.
