You might want to try Recuva. It’s from the same folks who made CCleaner, so it’s legit. The free version should be enough to recover those deleted files. I’ve used it a few times, and it did a decent job finding stuff I thought was gone for good. The interface is pretty straightforward too.
If you’re looking for something that’s a bit more feature-packed, give Disk Drill
a shot. They have a free version that offers a surprising amount of functionality for data recovery. It’s got a user-friendly interface, plus it supports a wide range of file types and storage devices. You can check it out at Disk Drill.
Meanwhile, if you’re a more technical user and don’t mind getting your hands a bit dirty, TestDisk is a great option. It’s open-source, free, and very powerful. The only catch is it doesn’t have the prettiest interface, and you might need to spend some time with the documentation to make sure you’re using it right.
Keep in mind, though – if your file system is particularly shot, you might need to go for a more professional tool. But for most accidental deletions, one of these should do the trick.
