Way 1. Search for large files using File Explorer

File Explorer is a resource management tool provided by Windows that can be used to view all the resources of this computer, allowing us to know more clearly and intuitively the files and folders of the computer. At the same time, it can help you manage files of different sizes and perform various operations on them such as: opening, copying, moving, deleting, etc.

1. Press Windows + E to open File Explorer. After the window pops up, click View at the top menu, then go to Show > Hidden items from the list to make the hidden files viewable.

Show Hidden Items

2. Locate to This PC, or go to the specific folders you want to search for large files.

3. Type * (an asterisk) in the search bar, which will display all the files on your PC. Then go to the Search tab and click the Size option to filter the results by large files only.

4. From the drop-down list, it will sort folders by size on Windows 11 thus you can select Large (128 MB - 1 GB), Huge (1 - 4 GB), or Gigantic (>4 GB) files depending on your real needs.

Show File Size

Alternatively, if you know the target files size, you can choose to locate the files by typing size: >1GB (for example) in the search field at the top right corner.

5. Once you find the large files, you can choose to delete them that you don't need in the search results to free up disk storage space.

This way, you can search for your files based on the size of the files in a specific folder or throughout your Windows 11 system.

Way 2. Find large files via Command Prompt

Windows Command Prompt is a powerful built-in tool that you can use to have it perform tasks. For example, repair Windows 11 using Command Prompt, troubleshoot system problems, run programs, or configure settings by typing different commands. Likewise, it can help you find large files on your computer and delete them with a command.

However, this method is more complicated and requires some background knowledge of computers. If you are a computer novice, then this method is not recommended for you. The specific steps are as follows.

1. Search cmd in the Search box, select Command Prompt, and then Run as administrator to open the window.

2. Type cd C:\ and press Enter to search the entire C drive. Continuously, type the following command: forfiles /S /M * /C "cmd /c if @fsize size(bytes) echo @path > largefiles.txt". You must replace the size(bytes) command with the specific file size you are looking for, which should be in bytes (B). (1 KB = 1024 B, 1 MB = 1,048,576 B, 1 GB = 1,073,741,824 B)

For example, if you want to find large files as 1 GB (1,073,741,824 B), you should input the command: forfiles /S /M * /C "cmd /c if @fsize GEQ 1073741824 echo @path > LargeFilesList.txt", and press Enter to run the command.

Large File List

3. Then it will create a folder named "LargeFilesList". You can go to File Explorer and open this folder to delete files and free up local disk space.
