Little tips - Free up Hard Disk space

Tired of receiving messages like "Out of disk space" or "Disk is full"? Two possible solutions:

1. Change your Hard Disk after saving all important data on an external support or spend hours and hours to burn DVDs and then install the operating system from scratch with all essential programs and loose a whole day to restore configurations
   


2. Free up disk space (no cost)
   

Except in special cases ("old" computers), you can free up space every time removing no longer useful and "hidden" files. The problem then is reduced to how to find these files: the rescue comes with a program for windows Windirstats (I discovered it in Linux with the equivalent kdirstat); it can provide a visual map of the files on your disk:

Each block represents a file and is more or less large in proportion to the size of the file. So it's easy to identify areas (grouped by directory) which are such as old movie .avi occupying space unnecessarily.

Of course you can analyze the files by scrolling the map or the folders tree, identifying for each space and the percentage associated.

I think it is a useful tool for identifying especially large files and would recommend to make careful what you delete (unless you know what it is) because some are system files and therefore essential to the operation of your computer.
