What is ExactFile?
ExactFile provides a comprehensive solution for file integrity verification through checksum calculations. It enables users to confirm that files copied to media like CD-ROMs or during backups remain unchanged and accurate. The tool supports multiple checksum routines including MD5, SHA1, CRC32, and RIPEMD, ensuring compatibility with various verification standards.
With multi-threaded processing, ExactFile efficiently utilizes CPU cores to accelerate scanning of multiple files. It handles Unicode file names without issues, making it suitable for international file systems. The software supports recursive directory scanning and processes very large files seamlessly. Available in both GUI and command-line versions, it offers flexibility for different user preferences while maintaining compatibility with popular checksum digest formats.
