How to Find Large Files on Windows 10

Step1: Open up File Explorer, and navigate to the location you wish to begin your search. If you search This PC, it’ll scan your whole computer, and if you select a drive within This PC, you’ll search for any files only on the selected drive.

Step2: In the search field at the top right of the window, type size: gigantic and then press Enter. This will search your specified location for any files larger than 128 MB.

Step3: At the top-left of the window, select the View tab, then choose Details. The search results will now have additional information, like file size, next to their names.
