WizTree scan and each folder size display

Since WizTree software supports the most widely used NTFS file system and directly reads the MFT file of the hard disk, the entire scanning and indexing process is very fast. MFT plays an important role in NTFS volumes, which has a great impact on its performance.

When the system allocates space and reads and writes disks, it frequently accesses MFT. Therefore, MFT has a crucial impact on the performance of NTFS volumes. Since the MFT can be used continuously to access all other files on the disk, it will also gradually become fragmented, resulting in longer disk access times. Developers of the NTFS file system reserve a specific area near the MFT to reduce Fragments in the MFT.


WizTree software not only finds the largest folder that is on the hard disk but also easily obtains a large list of files that occupy the most hard disk space.

Graphical Visual Treemap allows you to spot large files and large collections of smaller files at a glance. Simply click on any button and the disk files will be given right away (including the hidden files). If a large file in the list is a junk file, you can directly select it and press Shift+Del to delete it completely.
