Finding duplicate files on Windows 10 using the Command Prompt is a nifty trick to clean up your computer. By using a few commands, you can swiftly identify and manage those pesky duplicates that clutter your storage. This method is efficient and doesn’t require any additional software. In just a few steps, you’ll be well on your way to a tidier system.
How to Find Duplicate Files in Windows 10 Using CMD
In this section, we’ll guide you through using the Command Prompt to locate duplicate files on your Windows 10 system. This method will help you efficiently identify duplicates without relying on third-party applications.
Step 1: Open Command Prompt
Click the Start menu, type “cmd,” and press Enter to open Command Prompt.
Starting with Command Prompt is like opening the toolbox of your computer. You can access various functions from here. Make sure to run it as an administrator if you need deeper access to system files.
Step 2: Navigate to the Desired Directory
Use the cd command followed by the folder path to navigate to the directory you want to search.
Navigating to the right directory ensures you’re looking in the right spot. If you’re unsure about the path, you can always drag the folder into the Command Prompt window to automatically fill in the path.
Step 3: List All Files with Checksums
Type the command certutil -hashfile * MD5 to list all files with their checksums.
The checksum acts like a digital fingerprint for each file. By comparing these, you can spot duplicates easily. The MD5 algorithm works fine for this purpose.
Step 4: Analyze the Output
Look for files with matching checksums in the output.
If you see identical checksums, those files are duplicates. The output might be lengthy, so take your time scrolling through it to ensure you don’t miss anything.
Step 5: Remove Duplicate Files
Delete or move the duplicates based on your needs.
Remember to double-check before deleting anything. It’s a good idea to back up important files just in case you accidentally remove something you still need.
After completing these actions, you’ll have successfully identified and removed duplicate files from your system. This process helps free up space and can improve system performance.
