You can use a duplicate-file-finder application to scan your hard drive for duplicate files, which are unnecessary and can be deleted.

Additionally, we recommend you stay away from the registry cleaner in CCleaner and other similar applications. Don’t tick that option unless you’re absolutely sure. Warning: You can easily clear all of your saved passwords with CCleaner. However, if you don’t want to handle all of that manually, you can use CCleaner. CCleaner cleans junk files from a variety of third-party programs and also cleans up Windows files that Disk Cleanup won’t touch. RELATED: Here's What You Should Use Instead of CCleaner The same goes for just about any other program - if you can use the program itself to clean up temporary files, do so. Typically, you should clear the temporary files created by your browser from within the browser itself. (Your browser cache uses hard disk space to save you time when accessing websites in the future, but this is little comfort if you need the hard disk space now.) For example, it won’t clear Firefox or Chrome browser caches, which can use gigabytes of hard disk space. The built-in Windows Disk Cleanup tool is useful, but it doesn’t delete temporary files used by other programs.
