DiskSorter allows one to keep a user-specified number of reports in the reports directory or the reports SQL database while automatically deleting old reports and freeing up the disk space. These features are especially useful for fully automated file classification operations when the user needs to keep a history of report files in a reports directory or a history of reports in an SQL database.

By default, DiskSorter keeps all reports in the reports directory or the SQL database. In order to enable automatic report management, open the 'Options' dialog, select the 'Reports' tab and change the 'Report Files' or 'Report Database' options to appropriate values.

The 'Report Files' option is applicable to HTML, text, Excel CSV, XML and DiskSorter native reports saved to a reports directory or to the user's home directory using the DiskSorter command line utility. After saving each new report, DiskSorter will check if there are too many reports of the same type (HTML, XML, CSV, etc.) in the reports directory and delete old reports according to the user-specified configuration.

The 'Report Database' option is applicable to reports submitted to an SQL database using the DiskSorter GUI application or the DiskSorter command line utility. After saving each new report to the database, DiskSorter will check if there are too many reports from the same host computer, for the same set of disks or directories and delete old reports according to the user-specified configuration. For example, if reports from two different servers are submitted to the same SQL database, DiskSorter will keep in the database X last reports for each server.

The 'File Categories' option allows one to enable/disable exporting of file categories to HTML, text, Excel CSV and XML reports. Second-level file categories are available when reports are saved using the DiskSorter GUI application manually. Automatically generated reports or reports saved using the DiskSorter command line utility always saved without file categories. When the 'File Categories' option is enabled, DiskSorter GUI application will save second-level file categories to HTML, text, Excel CSV and XML reports.

The 'Compressed Reports' option allows one to save automatically generated HTML, text, Excel CSV and XML reports as compressed archive files.
