With the **improvement in the quality of media files, games and software** , our computer systems are becoming hungrier for more storage space with every passing day. No matter how huge your system’s hard drive is, you’re eventually, **going to see the low storage error**.

When that time comes, **you can either delete the unrequired data** or move the big files to an external hard drive to free up some disk space. And for this purpose, you’ll need the **help of a disk space analyzer tool** that’ll **show all your data in an easy to understand format** and help you manage it.

So, let’s check out my top picks of 10 best disk analyzer software for Windows to **free up storage in your PC**.

#### 1. [WinDirStat](https://windirstat.net/)

It may not be one of the most beautiful tools, but is definitely one of **the most reliable disk analyzers** you’ll ever find. WinDirStat is a fast analyzer tool that has three default panels to **show you information about your hard disk space**.

Below you will see a **treemap of the data shown in bars of varying size based on their actual size on the hard drive**. It makes it very easy to see which type of files are taking the most space.

There is a column on the right **listing all the file types** along with a treemap bar color to quickly find them in the tree map. And of course, there is a fully **intractable file explorer section where you can skim through your data** and delete, move and manage it as you please.

##### Takeaway

- Shows treemap.
- Easy to pinpoint file types and their size.
- Built-in cleanup options.

#### 2. [DiskSavvy](http://www.disksavvy.com/)

DiskSavvy is a **highly advanced disk analysis tool** that offers great customization options while still being easy to use. Its free version is more than **enough for regular users** , but if you **want to scan TBs of data** and require advanced features like network drive support or command line support, then **you’ll have to upgrade** to the [**paid versions**](https://www.disksavvy.com/purchase.html).

Although it **only shows data along with its size** , it has a special filters section that lets you see data using handy categorize. Some of these categories include, **by extension, modification time, accessed time, creation time, user name** a few more. You can also use pie and bar charts, but they aren’t interactive.

##### Takeaway

- Comprehensive filtering system.
- See top 100 large files.
- Plugin support.

#### 3. [SpaceSniffer](http://www.uderzo.it/main_products/space_sniffer/index.html)

It has an **interactive interface** that makes it very easy to differentiate between files/folders and installable programs. I really liked its touch of animations that **make the program look cool** , but at the same time **help visually pinpoint data easily.**

All the **data is shown as titles with the name of file or folder** written on it. You can double-click on each title to dig deeper and look for large files. You can export the data to a file and also **scan external storage devices**. I also really liked its **“More detail”** feature that shows you more details about a selected drive as you click on it.

##### Takeaway

- Offers great visual representation with animations.
- Easily dig deeper into folders.
- Scan external storage devices.

#### 4. [TreeSize](https://www.jam-software.com/treesize_free)

TreeSize has **both free and paid versions, but the free version works great** if you want something quick and simple. If you are not a fan of tiles, charts or treemaps, then TreeSize **free version will definitely attract you**.

It simply shows **all the folders and files in your drive along with their size** written next to them. The data is also arranged from big files to small, so you can **easily pinpoint the culprit**.

Its **paid version for personal use** shows **3D charts and treemaps** for proper illustration and you it can even pinpoint duplicate files. If you are interested in **scanning network drives and servers** as well, then you’ll need [**TreeSize professional version**](https://www.jam-software.com/treesize/editions.shtml).

##### Takeaway

- Very easy to use with simple interface.
- Shows data in GBs or percentage.
- Great illustration features in the paid version.

#### 5. [GetFoldersize](https://www.folder-size-explorer.com/)

GetFoldersize is a bit **similar to TreeSize free version** as it also only shows folders and their size on the hard drive. However, it **comes with additional tools** as well that you may find interesting.

Apart from the folders panel, there is another panel that **lets you see only the files inside the selected folder**. Additionally, results in both of the panels can be filtered just by **entering file extension or name of the files/folders**.

Best of all, **it can also scan network drives and list data inside it**. One drawback though is that I found GetFoldersize to be very slow as compared to many other tools in this list. And it also has **fixed view in GBs, MBs or KBs, so it a little hard to track exact size** of too big or too small files/folders.

##### Takeaway

- It can scan network drives.
- Makes it easy to differentiate between files and folders.
- You can filter results.

#### **6.** [JDiskReport](http://www.jgoodies.com/freeware/jdiskreport/)

JDiskReport has a really **sleek interface with many handy features**. What I **didn’t like about it** is that its scanning is so painfully slow, that I didn’t even wait for the whole disk scan. However, it **does an eye-opening job of showing details** and no other free program can even come close to it.

To start with, **it shows all the data in an intractable pie chart with both files and folders size** written on it. You can also get a pie chart for file extension types to see which type of files are the problem. Furthermore, there is a really helpful **“Top 50”** section that **shows top 50 large files in any location you select**.

On top of that, you can **see data by modified time to see which files you don’t use often** and get rid of them.

##### Takeaway

- See top 50 large files.
- Interactive interface.
- Reliable representation using pie charts.
- Built-in themes to change UI look.

#### 7. [HDGraph](https://www.hdgraph.com/)

If you like interactive stuff with animations, then HDGraph might work for you. It **draws a circular ring based chart that shows largest data** in the middle and then moves outward showing further data inside each folder. You can **double-click on each section to further investigate** it and the same chart rules will be applied to each section.

The **chart is fully interactive and can be customized** to your liking, from text to type and size to density. It does a good job of showing data, but it **doesn’t let you directly interact with the data itself** , which makes things little cumbersome.

##### Takeaway

- Interactive chart.
- Shows all in-depth information right on the chart.

#### 8. [WizTree](https://antibody-software.com/web/software/software/wiztree-finds-the-files-and-folders-using-the-most-disk-space-on-your-hard-drive/)

Another very **simple disk analyzer tool that only shows data in GBs** and formats it from large to small files. It is incredibly fast as well (3 seconds in my case) and goes a little further by **showing total items, percentage size, total files and folders, and last modified date**.

Interestingly, it also has a handy **“File view”** section that only shows files in a specific area with all the details like size or modified date. Moreover, you can use a **search bar to quickly pinpoint required files** and interact with them from its interface.

##### Takeaway

- Show extensive details about the data.
- Very fast processing.
- Handy File view section.

#### 9. [TweakNow **Diskanalyzer**](https://www.tweaknow.com/HDAnalyzer.php)

TweakNow Diskanalyzer has **two main sections, General and Summary**. The General section simply lists all the data along with file/folder size. However, the **Summary** is where you can **do all the management**.

Here it shows **20 of the biggest files located on your hard drive** along with a handy category section where you can see data listed by their type.

There is also an **interesting section where unused file/folders are listed**. If you are not actively accessing any file or folder, then it will be listed here. A really **good feature for deleting unrequired data**.

##### Takeaway

- See top 20 biggest files.
- Find out unused files and folders.

#### 10. [FolderSizes](https://www.foldersizes.com/)

FolderSizes is a paid tool ($60 per license) with a 14-day trial, but it’s the best disk analyzer tool you can get. It is a **complete disk analyzer tool in terms of both storage type support and features**.

To name few of its features, **bar chart/pie chart/treemap representation support, disk reports** , shows both hidden and revealed data, scan filters, highly customizable search feature, **check usage trend, over 15 filters to search for files** and a whole lot more.

I also really liked its **details feature** where you can **hover your mouse cursor** over a folder to see all the required details to tweak it. Even with all these amazing features, FolderSizes is **incredibly fast in processing data and the interface works smoothly**.

##### Takeaway

- Shows extensive details about files/folders.
- Multiple representations of data.
- Customizable search feature.
- Can scan data in network drives and servers.

#### Final Words

If I have to give the **best disk analyzer software** tag to any one of them, then FolderSizes deserves it the most. Unfortunately, shelling out $60 just to clean up your PC **isn’t something regular users would be comfortable with**. Nevertheless, it could be a good solution for businesses and large teams.

For regular users, **I’ll recommend WinDirStat or DiskSavvy free version** , they both are easy to use and functional.

**Enjoy**

Add Directory Report to your list. It looks just like the MS-Explorer but always shows the folder size.
