ReFox remains the gold standard in this space. Its ability to decompile the full range of FoxPro executables, separate complex components into their original parts, and then recompile changes through a built-in compiler makes it an irreplaceable tool for any organization still relying on FoxPro applications.
Before you rush to buy a tool, understand the hard limitations.
While FoxPro decompilers are incredibly powerful, they cannot work miracles. Reconstructed source code will rarely look 100% identical to what the developer originally typed. foxpro decompiler
: Application files designed to run within the VFP environment. .FXP : Compiled procedural programs. .SPX : Compiled screen programs. .MPX : Compiled menu programs. .QPX : Compiled queries. Why Use a FoxPro Decompiler?
For advanced forensic developers, standard PE (Portable Executable) tools like Resource Hacker or specialized hex editors can extract the raw virtual tables and embedded DBF data bound inside a VFP executable, even if the p-code itself is partially obfuscated. Step-by-Step Guide to Recovering Lost VFP Source Code
To understand how a decompiler works, you must first understand how Visual FoxPro builds an executable ( .EXE ), application ( .APP ), or dynamic-link library ( .DLL ). [ Source Files ] (
They are effective at extracting raw code from older VFP compiles, though they may struggle with heavily obfuscated or encrypted VFP 9 binary structures.
Historically popular, UnFoxAll was a go-to for many developers in the early 2000s. While it may struggle with some of the more advanced features of VFP 9, it remains a capable tool for older legacy applications. The Technical Reality: Can Everything Be Recovered?

Using a FoxPro decompiler is not a magic “get source code free” card. Several factors can complicate or block the process entirely.
