Two US National Archives file analysis tools are now available for general use. Both are open-source Java applications.
The File Analyzer and Metadata Harvester “functions like a digitization Swiss army knife. The application allows a user to analyze the contents of a file system or external drive and generates statistics about the contents of the contained directories. The application can be used to generate checksum values to ensure the bit-level integrity of files after they have been copied to a new device. After a collection of files have been converted from one digital format to another, this application can verify that there is a one-to-one match of before and after files.”
The Video Frame Analyzer “is used to analyze technical properties of individual frames of a video file in order to detect quality issues within digitized video files. Within video files, the quality issues that might arise vary from collection to collection. This application allows the user to configure the tests to be performed against a file and to tailor those setting to a specific collection.”
