Fixity

 

Widely used in organizations large and small, Fixity is a free utility for automated monitoring and reporting on the data integrity of stored files.

Fixity scans a folder or directory and creates a manifest of the files, including their file paths and their checksums, against which a regular comparative analysis can be run. Fixity monitors file integrity through the generation and validation of checksums, and file attendance through monitoring and reporting on new, missing, moved and renamed files.
