Because drive letters change dynamically when plugging a USB drive into different target computers, hardcoding project paths (like D:\Projects ) will break your workspace.
Create a blank text file inside your portable directory and name it config.fpw . Open it and add the following lines to decouple it from system defaults:
A tool manager that acts as an ecosystem package manager for FoxPro developers.
If you need to maintain different hotfix levels of VFP 9.0 for various clients, installing them on a single machine can cause library conflicts. Portable folders allow you to run different builds side-by-side without interference. 3. Ultimate Mobility Visual FoxPro 9.0 SP2 Portable
Visual FoxPro 9.0 SP2 runs remarkably well on modern 64-bit Windows operating systems.However, portable setups on modern OS environments require a few adjustments:
Technical Guide: Creating a Custom config.fpw for Portability
While a portable VFP environment solves immediate mobility needs, it does not solve the long-term issue of OS compatibility. Visual FoxPro is a 32-bit architecture. As modern operating systems phase out legacy support, consider these robust alternatives: Virtual Machines (VMs) Because drive letters change dynamically when plugging a
The entire VFP IDE (Integrated Development Environment), compilers, and required dependencies are bundled into a single folder that can be stored and run directly from a USB flash drive or an external hard drive.
Next, create a custom config.fpw file in the same folder to redirect internal paths:

Alternatively, for runtime-only deployment (not the IDE), you can legally redistribute the VFP 9.0 SP2 runtime DLLs ( vfp9r.dll , vfp9t.dll , vfp9renu.dll , etc.) alongside your compiled EXE. That is a supported Microsoft model – but the itself is not redistributable and requires full installation.
