Whenever you press Delete on a file, it goes to the Recycle Bin to await its fate. You can still recover the file while it’s there, so if you change your mind it’s a few clicks away from restoring.
But when forget to empty your recycle bin for a while, it will clog up spaces in system and For those on smaller SSDs, every bit of space counts. Fortunately, if you often forget to empty the Recycle Bin, Windows 10 can periodically do it for you.
Open the Settings app by opening the Start Menu and clicking the gear icon. Choose the System entry, then the Storage tab. Here, look for the Storage Sense header and turn the slider to On. This will make Windows automatically remove temporary files that you don’t need, but you should tweak how it works by clicking Change how we free up space below the slider.
Make sure Delete files that have been in the Recycle Bin for over 30 days is set to On. If you’d like, you can also tell Windows to delete temporary files and those in your Downloads folder. Those are up to you.
Now, nothing will stay in your Recycle Bin for over a month. Take care when deleting files if this setting is turned on, because if you delete something with the intent of recovering it later and wait too long, it will be gone. For most people, though, the automatic emptying will provide some extra, much-needed space.
