Tree Size

Quickly determine what folders / files are using up the space on your hard drive.

This tool will scan the NTFS file structure and build a visual tree representation showing which folders are using the most space.

Ass you drill down through folders the display will dynamically update showing you the percentage of space used relative to the parent folder, the folder size in bytes (and also in a more readable format converted to TB / GB or MB depending on folder size), it will also shown you a count of files and folders within each folder, along with the last change time, access time and creation time.

You can also switch to the File Extensions tab and scan and get a breakdown of files by filetype (extension) and quickly see the location of a specific type of file e.g. .DOCX.

N.B. Requires drives to be formatted with NTFS file system for analysis, does not work with FAT/FAT32 or exFAT.
