Looking to free up some space on that Windows 11 machine? Yeah, cleaning out duplicate files is one of those things that sounds simple but can get a bit messy if you’re not careful. Sometimes, Windows’ built-in tools aren’t enough—or they just make you do too much manual work. The goal here is to find ways to identify and smash those duplicates efficiently so your storage isn’t clogged, and maybe even give your system a little boost. Whether you prefer poking around with File Explorer or using some third-party software, there are solid options — just depends on how much time you wanna spend and how comfortable you are with more technical stuff.
How to Fix Duplicate Files Taking Up Space in Windows 11
Use File Explorer Search to Find Duplicates
Ok, so first method — it’s kinda old school but still works. Open File Explorer, then head over to your drive or folder where you think duplicates might be lurking. In the search bar, type something like *.jpg or *.mp3 to look for specific file types. You can even search for all files by just typing *.* but that might overload your results if you’ve got a lot of data. Once you get the results, sort by Name or Size — duplicates tend to show up next to each other if they have the same name or size. It’s kinda tedious but on some setups, it gives you a quick look at your unnecessary copies without extra tools. Just bear in mind, it’s easy to overlook duplicates, especially if they’ve been renamed or moved around.
Note: Sometimes, Windows can be slow or glitchy with searches, so patience is key. Also, keep in mind this method might miss duplicates that are in different folders or deeply nested.
Install a Third-Party Duplicate Finder Tool
This is probably the better way if you want to save time and avoid the manual grind. Download trusted apps like CCleaner or Duplicate Cleaner. These tools are built specifically for finding duplicates across multiple folders, even if they’ve been renamed or moved. They analyze file content, not just names, so they’re pretty accurate and much faster.
Once you install, run the scan. Usually, these apps let you select specific folders or drives—sometimes even media libraries or cloud folders if you set it up right. Expect a list of duplicates, and most programs give you options to preview files before deleting. Just double-check because accidently deleting something important is no fun.
Scan Your Files and Review Duplicate Results
Run the scan using your chosen software. For example, in Duplicate Cleaner, you specify your folder hierarchy, choose your match criteria, and hit analyze. The tool will crawl through and give you a neatly organized list of duplicates with details like file size, path, and date. This is the part where you need to be careful—review each duplicate pair, especially if they’re in system folders or application directories. Sometimes, what looks like a duplicate isn’t—like a backup or temp file. On some setups, the software might find false positives, so don’t just click delete without a second look.
Delete Duplicates Safely
If everything looks good, select the files you want gone and confirm deletion. Many tools give you options to send files to the Recycle Bin or permanently delete—preferably, go for the recycle bin for safety’s sake. After deletion, your drive will regain some space, and your system might breathe a little easier. Remember, on some machines, this process might fail on the first try—rebooting or rerunning the scan can help. Always back up if you’re unsure about what’s safe to delete, especially if you’re dealing with folders containing various file types or important documents.
Honestly, managing duplicates regularly can keep your storage neat and your PC running faster. The trick is to find a routine that works for you — manual searches now and then or automated scans once a month. Either way, keeping an eye on duplicate files should be part of your regular cleanup routine.
Tips for Efficient Duplicate Cleanup in Windows 11
- Always back up before hitting delete — better safe than sorry.

- Update your duplicate removal tools to get the latest fixes and improvements.
- Try cloud storage or external drives for big files—keep them out of local clutter.
- Double-check file paths before deletion — no accidental deletes of good stuff.
