Use the File Lister to get listings of your files and folders into Excel. That can help you analyse disk space usage, and you can sort and analyse your files and folders across different folders. Use Excel tools like sort, pivot, and graph to visualise your files and folders.
The File Lister can help you spot duplicate files, and having identified them you can use the File Manager to delete them.
You can also use the listing to bulk rename, copy, move, delete files and folders. Use your knowledge of Excel formulas to create new names, and then use the File Manager to bulk rename/copy/move.
