# Users manual {#users-manual}

-   Install the extension from the TYPO3 Extension Repository or composer (package name: mediaessenz/diskusage)
-   Click on the new backend module icon below the normal file list module
-   Choose a storage folder to see disk usage of all underlying files (incl. subfolders)
-   For files with references double click it to get detail infos
-   For files without references click on it and choose "More Info" or "Delete"
-   Restrict the result to only not referenced files by clicking on the corresponding button.
    This is useful to find no more needed big files quickly and easy
-   Beside the folder tree, it is also possible to get deeper into a directory by double clicking the
    corresponding group header
-   Be sure to update your reference index, before deleting any files!!!
-   Also keep in mind, that some files maybe linked directly and therefore have no references!
