Magic Bytes
Offset: 14
C0 48 42 41 4D 37
The FP7 format is a legacy proprietary database file type developed by Claris International Inc. specifically for FileMaker Pro versions 7 through 11. It serves as a self-contained structure storing relational data tables, user interface layouts, automation scripts, and media assets within a single document. Superseded by the FMP12 format in 2012, this legacy container requires conversion for use in modern FileMaker clients and is generally considered safe.

Python
