Best disk space analyzers for Windows

Here are some of the best windows disk space analyzer we found useful:


This hard drive space analyzer is the best for all-around use. WinDirStat has a user-friendly interface that enables the user to understand all the data on flash drives, external hard drives, and internal hard drives.

Additionally, the HDD space visualizer for Windows allows the user to set up cleanup commands and delete the data manually within the program. The setup commands can be customized, letting users add up to ten commands to run different files.

We found this feature particularly useful when adding functions to the program that the computer hardly supports. As such, instead of moving large files from a small hard drive to a large one, I only needed to create a simple command to expedite the process.


You will love the SpaceSinffer animated interface; it made it easy to scan through data files. Once the software is installed, you only need to choose the drive you want to be scanned, and SpaceSniffer begins to analyze its contents.

The results are represented in medium, large, and small rectangles, depending on the size of the file. You will find the arrangement a little cluttered, but it turned out an effective way of finding out the contents on the hard drive.

The software also has a zoom-in feature for viewing the details of each file or folder. SpaceSniffer is also a disk space analyzer freeware for users who want to try it out before purchasing the software.

Its automated software updates and scheduled tune-up times made it easy to schedule clean-up without supervision. The tune-up time is flexible (a few minutes to an hour), depending on the state of the hard drive. Glary Utilities software is also available in a free version.


The newest version of the SpaceMonger software is the fastest disk space analyzer. It provides a graphic Tree-map representation of folder and file sizes, making it easy to find files that need to be deleted.

What’s more, it is equipped with cloud storage capabilities that are available on Dropbox, Microsoft OneDrive, and Google Drive. We also found its custom search and filtering features are handy for users who want to isolate files consuming large storage space.


TreeSize is another excellent software if you’re looking for a free hard drive space analyzer. The portable version allows you to use the software without installation and carry it in a flash drive or other portable devices. TreeSize software is designed to scan through internal hard drives, flash drives, external hard drives, and internal hard drives.

We also found it effective at analyzing single folders from within storage mediums. The analyzer provides a tree view of the files and folders, making it easy to identify data eating up most of the disk space.

Folder Size (free 14-day trial)

It makes another excellent buy if looking for a free hard drive space analyzer for Windows 7. Folder Size is designed to display folder and file sizes, free space, and the percentage of disk size used in a tree view.

The program operates pretty fast as it scanned up to 40GB of files within minutes. It’s easy to customize the headings we want to display and choose their file sizes in the form of bytes and gigabytes. The software has a 14-day trial, but it’s best to purchase the premium plan to have a great disc space analyzer.


This free disk analyzer program provides up to five perspectives to help users understand Windows 2008 disk space usage. JDiskReport can scan single folders, including Google Drive, Dropbox, and sync online backup and cloud storage folders.

Once the software begins to scan through the data, it shows all the data in an intractable pie chart with folders and file sizes written on it. The Top 50 section was pretty handy as it showed the top 50 large files in any location we selected.

What’s more, the program not only shows the remaining free space but also where the largest files are stored. We also loved the fact that we could customize the interface settings to our liking.

Note that the app does not allow the user to open and delete the folder to avoid removing valuable files accidentally. It is another great software to check disk space in Windows.


This software scans through NTFS volumes in the shortest time. We tested it on our 256GB SSD and 2TB magnetic drive and we found that it took 1.4 seconds and 7.45 seconds, respectively, to scan the files. WizTree is available in a portable version, which makes it easy to store it in a USB stick or flash disk.

Once the software has scanned the files, it provides a graphical display with each folder proportionately sized based on the amount of space occupied. I found the second tab next to the tree view tab useful for finding individual files taking up lots of space. The tab displays up to 1000 large files on the drive.


The disk analyzer provides structured information about the amount of space used in the computer system and on network discs. Once the drives are scanned, the software organizes data in different formats to allow the user to choose the best classification method.

The files and folders are further categorized by size, date, user extension, and type. DiskSavvy is also equipped with special filters for files that contain music, pictures, and music. The filters also show the amount of space each folder occupies. You’ll also love the fact that you can create your own profile for the scanning and reporting processes.

Additionally, it suggests items we could remove to free up space upon clicking a specific category. While it does not have as many features as those discussed above, it is an excellent app for users who want to learn how to find disk space usage in Windows.
