Better Than Paid Apps

As the title suggests, better than paid apps. Also, it doesn't remove the files completely without consulting you, it just places them in the trash bin so you could check them out and put back anything that is necessary [some cache files make our lives developers quite useful even if large in size]
Should be paid in my opinion.

Amazing. Thank you.

Like a bad head cold, eliminating the dreck that had built up after two decades of OS-X was unending. Periodically I’d go in to delete caches etc but it was overwhelming. I checked about half the 11GB of deletions until I felt reasonably secure to blow it all out. While I know at some point I will have to do a clean install this puts that day(s) off a little longer.

Thank you so much.

Simple, Powerful & Effective

I've tried several other apps like this and this one seems to be the best. It's straight forward and simple to use. I had one glitch with the last panel to empty trash and support promptly answered my question. Thanks for a terrific app... and it's free! What more can you ask for?

Wow! Thank you for your kind words 😍
