How to Find Large Folders on Windows

This How.com.vn teaches you how to search for large folders on your Windows PC. The easiest way to do this is by using a free program called "TreeSize" to sort your folders from largest to smallest; however, you can also search for large files inside of your computer's File Explorer app if you just want to find your computer's largest files.

Searching for Large Files

While File Explorer can sort your folders by size, it will only show ZIP folders to you; normal folders won't be displayed. If you're just interested in finding large files to either back up or delete, however, you can use this method to find all of the large files on your computer.
2
Open File Explorer
. Either click the folder-shaped File Explorer icon in the taskbar, or type file explorer into Start and then click File Explorer in the search results.
- You can also press ⊞ Win+E to open File Explorer.
3
Click This PC. This tab is in the left-hand column of options. Doing so opens your computer's This PC window.
- If you want to search a more specific folder for large files, navigate to that folder using the folders in the left-hand column.
It's the text box in the top-right corner of the File Explorer.
Type size: into the text box, but don't press ↵ Enter yet.
6
Add a size parameter. Directly after the colon (:), type in one of the following:
- large — Displays items between 1 MB and 16 MB in size.
- huge — Displays items between 16 MB and 128 MB in size.
- gigantic — Displays items larger than 128 MB in size.
You should have size:large, size:huge, or size:gigantic typed into the search box.
Doing so will search your computer's hard drive(s) for all items (including folders) matching your search.
9
Sort the results. If you want to see the largest files you have, click the View tab at the top of the window, click Sort by in the "Current view" section of the toolbar that appears, and click Size. This will display the largest files that fall within your search parameters at the top of the File Explorer window.
- If you see smaller files displayed at the top of the window, either scroll down to view progressively larger files or click Sort by > Size again to switch the order.
