Despite being 32-bit, VFP 9.0 applications generally run well on 64-bit Windows 10 and 11 using the OS's compatibility layer. Key Features of VFP 9.0
Because VFP handles rapid file system I/O on tables and index files ( .cdx ), local antivirus scanners can drastically slow down processing speeds. Temporarily excluding your portable work folder from real-time scanning can drastically improve performance during heavy query execution. Future-Proofing: The Open Source Alternatives to VFP 9.0

For local, file-based data processing, the combination of Python and SQLite is highly efficient. SQLite requires zero configuration, stores data in a single cross-platform file, and mirrors the lightweight footprint that made VFP popular. Python provides extensive data manipulation libraries (such as Pandas) that surpass VFP's native querying speeds for massive datasets. XBase++ (Alaska Software)
