Decompilation of Visual FoxPro binaries is viable for source recovery and security analysis but yields imperfect artifacts and carries legal and security implications. Follow strict authorization, forensic practices, and remediation steps to mitigate risk and convert recovered code into maintainable, secure source.
A FoxPro decompiler is not a toy for amateur hackers. It is a specialized, professional recovery tool for legacy system administrators and developers facing a source-code crisis.
Verdict:
The best tool as of today remains ReFox for its reliability with complex VFP 9 forms, though DeFox is superior for encrypted files. Always run a trial version first.
And remember: Once you recover that source code, do the right thing. Put it on GitHub (private), back it up to three locations, and never let a legacy system hold your business hostage again. foxpro decompiler

A decompiler is a software tool that performs the inverse operation of a compiler. When you write a FoxPro application, you write human-readable code (.PRG, .SCX, .FRX). The compiler turns that into machine-readable p-code (pseudo-code) or binary inside an .EXE or .APP file. Decompilation of Visual FoxPro binaries is viable for
A FoxPro decompiler scans that compiled file and attempts to reconstruct the original source code, including:
It is important to note that no decompiler can reproduce the original variable names, comments, or formatting. However, a high-quality decompiler can recover the logic, functions, and database interactions with remarkable accuracy. The best tool as of today remains ReFox
Microsoft ended support for Visual FoxPro in 2015, but the ecosystem refuses to die. The open-source community has produced decompilers like “ReFox” (originally commercial, now legacy), “FoxyDecompiler,” and more recent tools integrated into migration platforms. As organizations increasingly move to cloud-based systems, demand for decompilation will spike temporarily — then decline as the last FoxPro apps are retired. However, because many government and financial systems run on FoxPro well into the 2020s, a solid decompiler remains a survival tool for IT consultants and in-house developers.
