OS X: they accumulate in the file to the trash, I never had a shortage of disk space inadvertently. Tool that can be used to prevent it is application "Empty" free. If dust would accumulate beyond the capacity that you set, you will tell the pop-up notification center.
Much the function of Empty. Is the presence that resides in the menu bar, who cares about the state of the usual trash. Capacity limit setting, you can change whenever you like. I tend to think of the real world, even garbage Tamekoma course not, but it's best, and with it a big trash "... do I throw away is now." Would be to keep your Mac clean, Empty helped me.
