One of the most useful features of DiskSorter Server is the ability to compare file classification reports saved in the DiskSorter reports database allowing one to easily identify how the disk space usage is changing over time. For example, the user can schedule a periodic file classification operation to be performed once per week and then compare two weekly file classification reports and see what exactly changed over the time.

In order to compare file classification reports, press the 'Reports' button located on the main toolbar, select two file classification reports, click the right mouse button and select the 'Compare File Classification Reports' menu item. DiskSorter Server will compare the selected file classification reports and display the change report dialog showing a list of changes in the disk space usage and/or the number of files per file category according to the file classification plug-in used for this specific file classification operation.

For example, if the file classification operation categorized files by the file type, the change report will show the changes in the disk space usage and/or the number of files per file type. On the other hand, if the file classification operation categorized files per user, the change report will display changes in the disk space usage and/or the number of files per user.
