What is a Disk Space Analyzer?
A disk space analyzer is a tool that can help you better understand how much storage capacity is being used by files and folders on your computer, as well as identify any areas where there may be issues with too little or too much free storage.
What is the purpose of disk space analyzer?
We all love computer games, software, and other applications. However, having too much of them on your computer can slow down the system.

Note that to perform a disk cleanup, you will need to delete files or transfer large files to your external hard drive.
This is where a space analyzer becomes useful.
A disk analyzer is a specialized software that scans your computer hard drive (or a specific folder) and analyzes the types of files stored in the dive to help you identify old or unnecessary files so that you can perform a disk cleanup and free up space.
A disk space analyzer will provide a detailed report on the types of files that occupy your hard drive and the amount of space used so you can know where your storage is wasted to help simplify disk cleanup and optimization.
