ExactFile is a Windows file-integrity (checksum) utility for creating and verifying file digests.
Key points
- Purpose: generate and test checksums to confirm files are bit‑perfect (useful for backups, CDs, transfers).
- Platforms: Windows GUI plus a console (exf) — supports Windows XP through Windows 10 (per download pages).
- Hashes supported: CRC32, Adler32, MD2–MD5, SHA‑1, SHA‑2 (256/384/512), RIPEMD, Tiger, GOST, and others.
- Features: multi‑threaded hashing, Unicode filename support, recursive directory scanning, handles very large files, benchmarking, create/test digest files, and create a small TestFiles applet to distribute with file sets.
- Status/licence: Freeware; site notes the program is no longer actively developed but is available for use (beta/stable versions historically listed).
- Common use cases: verifying backup integrity, checking CD/DVD/USB copies, producing digest files for distribution, scripting via the command‑line exf tool.
If you want, I can:
- provide download links and the latest version info, or
- give a short how‑to to create and verify a digest in ExactFile.
