FILE TYPES REPORT
The File Types report, shown below, classifies files by type based on file extension (e.g. .doc, .xls, .jpg, etc.). Complete file size, size on disk (allocated size), extension, and count information is shown for each file type.
Double-click any file type report row to view a list of files that match the associated file type.
FolderSizes also offers a File Categories report, which groups file types by user-configurable categories.
The file type graph view can switch between bar and pie graph modes. The bar graph view is shown above.
Find Out Which File Types Use the Most Disk Space
The File Types report groups files by extension so you can see exactly how much storage each type consumes - documents (.docx, .pdf, .xlsx), images (.jpg, .png, .gif), video (.mp4, .mov), audio (.mp3), and archives (.zip, .rar). Sort by total size to find the file types eating your disk space, then drill in to the individual files behind any type. Pair it with the File Categories report to group related extensions together, or the Largest Files report to target individual space hogs.
