Ccleaner is that any good?
The only disk cleaning tools you need are provided in Windows by default.
But either way, the Microsoft that makes random hardware demands for Windows 11 to turn computers into landfill isn't what I would take recommendations from. Or much anyone else, either. Just by using Revo Uninstaller I am just constantly amazed at how much stuff software leaves around in the registry and on disk. I recently uninstalled Keybase because I wasn't really using it but noticed it had accumulated 200MB of log files (for nothing, for running in the background basically), and after uninstalling it, RU found an additional 400+ MB of leftover files. And that just rubs me the wrong way, and even if it doesn't measurably slow down the use of the system, just having all sorts of orphaned and 100% useless data checked for changes every time a backup runs is reason enough for me to get rid of it.
FWIW, my system doesn't seem to get slower over time, and I do attribute that to caring too much about and fiddling with things I'm not supposed to care about. I don't recommend it to others -- if you know enough and care enough to do it, you're doing it already -- but you can pry that from my cold, dead hands.
Tinkering for tinkering's sake can definitely be fun though and there's nothing wrong with that. Sometimes poking at things, and sometimes breaking them, is a great way to learn new things or even just scratch a casual itch.
But while SSD changed everything obviously, in addition to daily partition-based backups I also make manual backups to my NAS with FreeFileSync, just so I don't have to restore full disks when I only want to pull a few files from the backup. While FFS is crazy fast checking for changed files, all those orphaned files are still not free... it's not about the size so much as about the number of files, doubly so when it goes over the network. I also rather often search my whole system for stuff, and there too, files and directories that don't exist are the quickest to search.
I wouldn't want to keep them around in the same way I wouldn't want to run a script that puts 100k tiny files with random content all over the place. Because it's just a pointless waste. And since I enjoy the process, I don't count the time I am using on that, so in my mind, I'm being frugal in a weird, misguided sort of way... I know I could spend the time to make more money and then just buy another HD, but I don't wanna :P
Especially when you make your own cleaners [0][1], which you can also can selectively invoke via the command line (and of course do that via schedule / cron etc.)
