You are moving from FoxPro to a modern platform like C#, Python, or a web-based PHP/SQL system. The decompiler helps you extract the business rules, data validation logic, and workflows from the compiled executable so you can accurately translate them, rather than guessing how the legacy system worked.

A decompiler like ReFox works by identifying and decoding these sections. It parses the PE (Portable Executable) file header to locate sections that a standard Windows disassembler might overlook—custom sections like .vfpdata , .foxres , or other markers that indicate VFP-specific content.
