NARA File Analyzer and Metadata Harvester
NARA File Analyzer can be used to analyze the contents of a folder or drive and export reports documenting findings. Among other things the program can be used to count the number of files by file type, create a directory listing, and generate checksums. (Windows and Mac* with Java installed)
The File Analyzer tool can be run as a GUI in which the results are displayed in a table. The File Analyzer can also be run in batch mode. In batch mode, the results will be written to a tab-separated file. The GUI version of the application allows the results of multiple executions to be merged. The merged information can be filtered to display matching values and mismatched values.
