The Size Maps tab of the Diagnostics page allows you to view your site’s files in either a graphical format (the Directory Size Map) or a listing with notes about exclusions from backups (the Directory Size Listing).
Directory Size Map
This Directory Size Map displays an interactive graphical representation of directories and the corresponding size of all contents within, including subdirectories. This is useful for finding where space is being used. Directory boxes are scaled based on size. Click on a directory box to move around. Note that this is a CPU intensive process and may take a while to load and even time out on some servers. Slower computers may have trouble navigating the interactive map.
To view the Directory Size Map, click Display Directory Size Map.
