Feeling curious as to which files taking up space on your hard drive? Windows 10 has a built-in tool for this, so you might want to try it out first before considering using a third-party app.
To use the tool, open Start menu and then Settings (or press Win key + i), select System, and go to Storage.
In the Storage section, you will see all of your drives listed on the right side along with their total and used spaces information.
Click on any drive to begin your investigation.
The scanning process may take a while the first time you use the tool, but it should take less time the next time you run it again.
Depending on which part that you select, the tool may give you option to perform file deletion or simply open the folder in question. For example, go to This PC drive, scroll down and click Temporary files. You will see options to delete files in there, like emptying recycle bin, clean temporary files and some other stuff like the files of your previous version of Windows.
Now go back to the drive list and select another drive to drill down into the detailed category view, and then click Music or Documents. A number of folders are presented together with their size information. If you click any of these folders, instead of giving you more information on which files that actually eat up the space on your hard drive, File Explorer will open to the exact location of the folder, and this is where this tool falls short.
All in all, in a situation where you need a quick glimpse of your hard drive space information, this Storage Sense may be able to help you to some extent. When you need a more comprehensive information, use tools such as WinDirStat.
Tip: you can pin Storage to Start menu for a quicker access
