In order to classify files located in one or more disks, directories or network shares, press the 'Classify' button located on the main toolbar, add directories or network shares that should be processed, select an appropriate file classification plug-in and press the 'Classify' button.

Depending on the number of files that should be processed, the file classification process may take from a couple of seconds for thousands of files to a few minutes for large file systems containing millions of files. During the file classification process, DiskSorter will display the file classification results preview, the total number of processed files and the total amount of processed disk space.

Once the file classification process is completed, DiskSorter will display a hierarchy of file classes and categories sorted by the amount of the used disk space. For each file class or file category, DiskSorter will show the name of the category, the total number of files in the file category and all subcategories and the total amount of the disk space used by all files in the file category and all subcategories.

In order to display a pie chart showing the amount of the used disk space per file category, press the 'Charts' button located on the main toolbar. In order to open a file category, click on the category item in the main file classification results view. Select one or more categories, classes and/or files and press the right mouse button to perform a file management operation on the selected items. For example, select a file category, press the right mouse button and select the 'Copy To' menu item to copy all files related to the selected file category to a directory.
