• Sparse file method (fast, uses little disk space logically): create a sparse file that appears to be 50 GB but consumes minimal physical storage until written. Useful for testing filesystem metadata and behavior but not I/O throughput.
• Filled file method (real data, for throughput tests): generate a 50 GB file filled with pseudo-random or repeated patterns to force actual disk I/O and network transfer. Use cryptographic-quality randomness if uniqueness matters, or repeated patterns (zeros, fixed bytes) if compressibility/dedupe characteristics are part of the test.
• Chunked generation: Build the file in smaller chunks (e.g., 1 GB blocks), which eases resume on failure and facilitates parallel generation.

1. Open PowerShell and navigate to the directory where you want to create the test file.
2. Run the following command: fsutil file createnew testfile 50GB
3. Wait for the command to complete. This may take a few minutes.
