eliminate obsolete files?

[telegiovi]

When I was upgrading to ubuntu 12.04, a window asked me if I wanted to cancel 104 obsolete files. I had no time and did not cancel the files. Can I do it now? The new ubuntu is already running. How could I do?
Thanx

You probably don't have a problem unless you have very old hardware with a tiny hard disk.

However, you can open a terminal and enter the following two commands to clear out old installation files and redundant installed applications:

sudo apt-get autoremove
sudo apt-get clean
