Our computers need more storage space on a daily basis as a result of the improvement in the quality of media files, games, and software. No matter how large your system’s hard drive is, the low storage error will eventually appear.
When that time comes, you can free up some disc space by either deleting the unnecessary data or moving the large files to an external hard drive. You’ll need the aid of a disc space analyzer tool for this objective, which will show all of your data in an understandable format and assist you in managing it.
So let’s look at my top 10 recommendations for the best Windows disc analyzer programmes to free up space on your computer.
10+ Free Data Recovery Tools (Windows)
If you work in a profession where data is important, whether it be for documents, media, finances, or anything else…
1. WinDirStat

It might not be the most attractive tool, but it is unquestionably one of the most trustworthy disc analyzers you will ever find. WinDirStat is a quick analyzer tool that provides information about your hard disc space in three default panels.
The data is displayed below as a treemap with bars that vary in size according to their actual size on the hard drive. It makes it very simple to identify the file types that are occupying the most space.
Takeaway
- Shows treemap.
- Easy to pinpoint file types and their size.
- Built-in cleanup options.
2. DiskSavvy
All file types are listed in a column on the right, along with a colour for the treemap bar so you can find them easily. Additionally, there is a fully unbreakable file explorer section where you can browse your data and edit it as you see fit.
DiskSavvy is a highly sophisticated disc analysis tool that is simple to use and has excellent customization options. Regular users can scan TBs of data with its free version, but if you want advanced capabilities like network drive support or command line assistance, you’ll need to subscribe to the expensive editions.
Takeaway
- Comprehensive filtering system.
- See top 100 large files.
- Plugin support.
3. SpaceSniffer
It contains a particular filters area that allows you to see data using helpful categorization even though it merely displays data together with its size. By extension, some of these categories include user name, creation time, accessed time, and modification time. Pie and bar charts are other options, but they are not interactive.
It offers an interactive interface that makes identifying files, folders, and installable programmes a breeze. I loved how it added animations to make the software look interesting while also making it easier to visually identify data.
Takeaway
- Offers great visual representation with animations.
- Easily dig deeper into folders.
- Scan external storage devices.
4. TreeSize
Titles containing the name of the file or folder are displayed for all of the data. For more information and to search for huge files, double-click on each title. The data can be exported to a file, and external storage devices can also be scanned. I also really loved itsMore detailfeature that offers you additional details about a selected drive when you click on it.
TreeSize includes both a free and a paid edition, but if you just want something quick and easy, the free version is fantastic. If tiles, charts, or treemaps are not your thing, the TreeSizefree version will undoubtedly catch your attention.
The drive’s folders and files are simply displayed, along with their sizes written next to them. Also, the data is organised from large to small files to make it simple to identify the offender.
Takeaway
- Very easy to use with simple interface.
- Shows data in GBs or percentage.
- Great illustration features in the paid version.
5. GetFoldersize
the paid-for version for private use
provides treemaps and 3D charts for correct illustration, and it also allows you to find duplicate files. You’ll need the TreeSize professional edition if you’re interested in scanning network drives and servers as well.
Although GetFoldersize only displays folders and their sizes on the hard disc, it is quite comparable to TreeSize’s free version. Yet, itcomes with additional toolsas well that you may find fascinating.
Takeaway
- It can scan network drives.
- Makes it easy to differentiate between files and folders.
- You can filter results.
6. JDiskReport
A panel that just displays the files in the specified folder is available in addition to the folders panel. Also, both panels’ results can be filtered simply by inputting a file extension or a folder’s name.
The best part is that it can also scan network drives and list the contents of them. Nevertheless, compared to many other programmes on this list, GetFoldersize is relatively slow, which is one disadvantage. Moreover, it has a fixed view in GBs, MBs, or KBs, making it challenging to determine the exact size of excessively large or small files or folders.
The interface of JDiskReport is extremely slick and offers a tonne of useful features. Its scanning is so agonisingly slow that I didn’t even wait for the entire disc scan, which is what I didn’t like about it. No other free programme comes close to it in terms of how well it reveals details, though.
Takeaway
- See top 50 large files.
- Interactive interface.
- Reliable representation using pie charts.
- Built-in themes to change UI look.
7. HDGraph
It first displays all the data in a difficult pie chart with the sizes of the files and folders inscribed on it. You can also get a pie chart for file extension kinds to see which sort of files are the problem. The Top 50 option, which displays the top 50 huge files in whatever location you choose, is also quite helpful.
Also, you can view data by changed time to determine which files you don’t use frequently and delete them.
Takeaway
- Interactive chart.
- Shows all in-depth information right on the chart.

an a…………….. It creates a circular ring-based graphic with the largest data in the centre and more data inside each folder moving outward from that point. The same chart rules will be applied to each area if you double-click a section to explore it further.
8. WizTree
The chart can be entirely adjusted to your preferences in terms of text, font, size, and density. It performs a fantastic job of displaying data, but because you can’t interact with the data directly, things are a little awkward.
