When that time comes, you can either delete the unrequired data or move the big files to an external hard drive. 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.


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.

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.

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.
