In Windows there were many crap files that inflated the system (like temp, browser temp, update fragments, old update files and so on). So in Windows there were tools like CCleaner really needed.
What about Ubuntu? Are there such tools also needed? Or does Ubuntu delete such files automatically?
If such a cleaner is needed (or useful), what cleaner do you recommend?
In the terminal run sudo apt-get autoclean
Entry in man apt-get for autoclean
autoclean
Like clean, autoclean clears out the local repository of retrieved
package files. The difference is that it only removes package files
that can no longer be downloaded, and are largely useless. This
allows a cache to be maintained over a long period without it
growing out of control. The configuration option
APT::Clean-Installed will prevent installed packages from being
erased if it is set to off.
You can use BleachBit, you can also find it on Software Center. It's really good, I use it for a year and I'm satisfied.
As Alexis Wilke said, most of the cleaning is done automatically by the system, but a lot of programs do not clean after themselves and you may want to clean their crap (just for freeing space on your system).
You can do that with a little tool called bleachbit, you can install it in software-center, and run from the menu.
You can run is as normal user - when it cleans your files, or as root, then it cleans also system files and for other users.
Of course you can choose what to clean.
