find large pc files

Is your laptop’s or desktop’s hard drive more than 75% full? If so, you need to free up some hard drive space. Erasing temporary files with disk cleaner software is one good way to free up some storage space.

Alternatively, you can free up hard drive storage by manually deleting some of your largest files. To do that, you’ll need to find the largest files on your desktop or laptop first.

How do I search for files by size in Windows 10?

Method 1: Find Your Largest Files With File Explorer

Although many users utilize Cortana to search in Windows 10, File Explorer remains the best built-in utility for file searching. Explorer is the file manager in Windows that includes numerous hard drive search options.

You can find your PC‘s largest files with the options on Explorer’s Search tab. This is how you can find your largest hard drive files with File Explorer.

  • First, press the File Explorer button on the Windows 10 taskbar.
  • Select your C: drive or an alternative drive partition to search for files on. Alternatively, you can select a specific folder to search for files in.
  • Then click inside the Search box on the right of Explorer’s window to open the Search tab shown directly below.

  • To search all subfolders included within your selected drive partition or folder, select the All subfolders option highlighted in the snapshot directly below.

  • Click the Size button to open the drop-down menu shown below.

  • Select the Gigantic (>128 MB) option to search for the largest files. File Explorer will then list all files that eclipse 128 MB within your selected directory or drive.
  • Alternatively, you can manually enter ‘size:>128MB’ in the search box as shown directly below. By entering ‘size:>’ in the search box, you can also modify the search criteria by entering other values.

  • To further modify your search, press the Type button. Then you can select to search for a more specific file type, such as image, music or video.

  • When File Explorer has listed files that match your search criteria, you can erase files by selecting them and pressing the Delete button.
  • Deleted files usually go the Recycle Bin. Thus, you’ll also need to select the Empty Recycle Bin option in the Recycle Bin to erase the deleted files.

You might find that some of your desktop’s or laptop’s largest files are system files in subfolders within the Windows folder. Never delete any large file that might be a system file. If you’re not sure whether a file is a system one or not, do not erase it. Stick to deleting the largest image, video, document and other files within your user folder.

File Explorer might also find large program (EXE) files. Don’t delete program files from within Explorer as they’ll probably be listed within the Programs and Features Control Panel applet.

You can delete software files by pressing the Windows key + R hotkey and entering ‘appwiz.cpl’ in Run. That will open the window shown directly below from which you can uninstall software.

Method 2: Search for Files With Largest File Finder

Largest File Finder is a third-party software alternative to Explorer’s Search tab that finds and lists the largest files on Windows desktops and laptops. However, it isn’t exactly a search utility as it doesn’t include any options to find specific files.

You can save Largest File Finder to a folder by clicking the Free Download button on this page. Then you can open the window below by clicking top100files.exe.

When you launch Largest File Finder, it will automatically search for the largest files on the C: drive and list them according to file size. You can press the Stop button to halt the scan early.

Then you can press a Browse button to select a more specific folder for the software to scan. To erase files within LFF, right-click them and select the Delete option.

So that’s how you can find and delete the largest files on your PC with Explorer and Largest File Finder. Erasing large files will certainly free up quite a bit of hard drive space.

Even if you need to keep some of your largest images, videos or documents, you can still free up HDD space by moving the files from your hard drive into Google Drive or OneDrive cloud storage.
