Q: file cleaning

There are maintenence routines that run every night, the only problem is that your system must be up and running for this to happen.

OS X is a very robust operating system and pretty much takes care of itself.

In my testing of the supposed "cleanup" applications, I have found them to be either worthless or dangerous.

For those reasons I strongly recomend against their installation and use.

OS X does not require defragmenting like Windows and maintains itself very well without the use of third party cleaners.

See > Mac maintenance Quick Assist

I also found > Mac OS X Maintenance Myths - YouTube to be very informative.

So basiclly "If it's not broken, don't try and fix it"

The closest you can get to a general “tune-up,” is the Safe Boot, followed by a normal reboot. Combine this with verifying/repairing permissions from Disk Utility after software installs/updates.

Prior comments apply as OS X is quite robust in the absence of “tinkering.”
