AVPreserve is pleased to announce the release of Fixity and MDQC, two new free and open-source digital preservation tools available for free download on our Tools page. 

Fixity is a utility for the documentation and regular review of stored files. Fixity scans a folder or directory, creating a manifest of the files including their file paths and their checksums, against which a regular comparative analysis can be run. 

MDQC stands for Metadata Quality Control, and it reads the embedded metadata of a file or directory and compares it against a set of rules defined by the user in order to perform automated review of embedded metadata.
