How to find the largest files in Windows 10?
You don’t need any additional software to do this, because Microsoft has built this functionality right into Windows. And you can access it from anywhere on your PC with just a few clicks.
Open File Explorer and navigate to the location where you want to start your search. If you search This PC, it will scan your entire computer, and if you select a drive within This PC, it will only search for files on the selected drive.
In the search field at the top right of the window, type size:gigantic and press Enter. This will search your specified location for files larger than 128 MB.
