These days, a relatively clean and uncomplicated Windows 10 or 11 system disk might be home to more than 250,000 files and 90,000 folders. A more complex, application-heavy system disk might contain between half a million and a million files. My Windows 11 production PC has over 970K files and 275K folders, for example. That’s a lot of stuff!
Indeed, all those files need not necessarily be kept around. That’s why it’s a good idea to practice regular disk hygiene. This is exactly what is explained and explored here, with plenty of examples and screen shots to illustrate the cleanup process. Best of all, the tools that help you tidy up won’t cost you a dime.
