How to find large files on Windows with IObit large file finder:

Step 1. Download and install Advanced SystemCare on your Windows PC. Launch it.

Step 2. Open the Toolbox on the top-right corner and select Large File Finder. This requires a quick installation.

Step 3. Choose the drive(s) you want to scan and set the file size you want to search. Then start the scan process.

Step 4. Review the largest files found, select unnecessary items, and delete them to recover storage.

If you do not want to install additional software, Windows also includes several built-in options to locate and clean large files. These methods are free and work well for occasional cleanup. However, they usually require more manual steps compared with a dedicated large file finder.

Method 1: Use File Explorer to Find Large Files

File Explorer is the simplest built-in option when you want to find large file Windows users have stored on their computers.

Follow these steps:

Step 1. Press Windows + E to open File Explorer.

Step 2. Select This PC or the drive you want to scan.

Step 3. Click the search box in the top-right corner. Enter a size filter, for example: size: >1GB. Windows will search for files larger than 1GB.

After the search finishes, switch to the Details view and sort files by size to identify the biggest items.

Advantages of File Explorer

• No additional software required

• Easy for beginners

• Works directly inside Windows

Limitations

• No visual storage analysis

• Limited filtering options

• Requires manual review

• Cannot automatically clean other unnecessary files

• For users with large hard drives, searching manually can take considerable time.

Method 2: Use Windows Storage Settings

Windows Storage Settings provides another built-in way to understand what is using your disk space. To access it:

Step 1. Open Settings > System > Storage.

Step 2. Select your drive. Review storage categories. Windows will display space usage from categories such as:

• Installed apps

• Temporary files

• Documents

• Pictures

• Videos

• Downloads

Step 3. Click into the category you want to clean, check the boxes, and click Remove files.

This method is useful for checking general storage usage, but it is not designed specifically as a large file finder. It groups files by category rather than showing a detailed list of the biggest individual files.

Method 3: Use PowerShell to Find the Largest Files on Windows

For advanced users, PowerShell provides another way to find largest files Windows users may want to review. Unlike File Explorer, PowerShell allows you to run specific commands to search, sort, and display files based on their size.

To find the largest files on your C drive, follow these steps:

Step 1. Press Windows + X and select Terminal (Admin) or PowerShell (Admin).

Step 2. Enter the following command:

Get-ChildItem -Path "C:\" -Recurse -File -ErrorAction SilentlyContinue | Sort-Object Length -Descending | Select-Object -First 20 Name, Length, FullName.

Step 3. Press Enter and wait for Windows to complete the scan. The command will scan your drive, sort files from largest to smallest, and display the top 20 largest files.

However, PowerShell is not suitable for everyone.

• It requires command-line knowledge

• Can take a long time on large drives

• Results are not beginner-friendly

• Does not provide cleanup recommendations

For users who simply want to quickly find large files on Windows and manage them easily, a dedicated tool is usually a more convenient choice.

Windows tools are useful for occasional searches, while a professional large file finder provides faster scanning, better organization, and a more convenient cleanup experience. Here is a quick comparison.

For most users, Advanced SystemCare PC optimizer offers the quickest and easiest experience because it focuses specifically on locating oversized files rather than requiring manual searches or command-line tools.

Finding large files is only the first step. Before deleting anything, you should understand which files are safe to remove and which ones should be kept.

Large Files You Can Usually Remove

The following files are often safe to delete if you no longer need them:

• Old Downloads

• Large Video Files

• Old Backup Files

• Installation Packages

Files You Should Avoid Deleting

Not every large file is unnecessary. Avoid removing files from locations such as:

• Windows folder

• System32 folder

• Program Files

• Driver folders

• Recovery partitions

Deleting system-related files may cause Windows errors or prevent applications from working properly. When unsure, always check the file location and purpose before deletion.

Can I find large files on an external hard drive?

Yes. Most large files finder tools, including Advanced SystemCare Large File Finder, allow you to scan external HDDs, SSDs, USB flash drives, and other connected storage devices.

What file size is considered "large"?

There's no universal definition, but files larger than 100 MB are often worth reviewing. If you're trying to recover significant disk space, it's more efficient to scan for files over 500 MB or 1 GB.

Is it safe to delete all large files?

No. A large file isn't necessarily unnecessary. Before deleting anything, check the file type and location to make sure it isn't a Windows system file, application data, or an important personal file.

Why can't I delete some large files?

Some large files may be in use by running programs, protected by Windows, or require administrator permissions. Close any applications using the file, restart your PC if necessary, or use a trusted cleanup tool that can safely remove unnecessary files after confirming they're not system-critical.

Conclusion

Finding oversized files doesn't have to be difficult. Whether you use File Explorer, Storage Settings, PowerShell, or Command Prompt, Windows offers several ways to locate storage-consuming files.

However, if you regularly need to organize storage, Advanced SystemCare large file finder provides the fastest and most convenient solution. With customizable scan sizes, quick sorting, and one-click deletion, it makes identifying and removing unnecessary large files much easier than manual searching, helping you recover valuable disk space in just a few minutes.
