ReFox XII, developed by Jan Brebera and distributed by ComPro (CZ), is widely regarded as the most comprehensive and professional FoxPro decompiler available. It is often cited as the “first choice” in developer communities such as Foxite and Stack Overflow.
Never use a decompiler to steal proprietary algorithms or bypass licensing. This article promotes recovery, not piracy.
While the best tools are excellent, you may lose comments, variable names (if obfuscated), or specific project configuration settings. Conclusion
: Restoring damaged source code or verifying if current code matches a compiled executable.
Apply external VFP obfuscators that scramble variable names, destroy formatting, and inject dummy loops to confuse reverse-engineering software.
Ensure the tool supports the exact version of FoxPro or Visual FoxPro used to create your application. If you need to recover source code from VFP 9.0 (the most recent version), ReFox XII is your only reliable choice.
It attempts to reverse-engineer compiled VFP executables back into .prg , .scx , .vcx , etc. — reconstructing forms, reports, and procedural code.
I used FoxPro to resurrect a tiny municipal payroll system. The binary had been compiled on a machine that died the night before a thunderstorm took the council's records. FoxPro reassembled the logic of late-night fixes, the ad-hoc workarounds, the structures named "fixme_2005." It annotated them: "This block circumvents tax rounding for contract type C; keep only if local law requires." I could have optimized it into a sleek service running containers and linted libraries, but I left the "fixme" as a comment. The payroll clerk who read the output laughed and cried at the same time—she recognized the coder, a colleague who had left for another town years ago.
It wasn't a fox from the forest but an emulation of one—a small daemon called FoxPro, named years before anyone remembered why. It lived in the slow hours between backups, in a stack of nightly images and orphaned executables. Administrators called it a utility once: a decompiler that stitched machine whispers back into rough human sentences. In the beginning it had been useful: vendors and hobbyists used it to recover lost source, to learn, to patch, to translate. Over time, though, it became myth — the "full version" whispered about on message boards, a legendary binary that did more than reverse: it reasoned.
