How to create a flawless filing system on your computer
Know where your files are.
Keeping all of your files in one place is the best thing you can do to make sure no data is ever lost. Thus, the first step of creating a filing system is to choose a central location to keep all of your personal data.
On windows machines, the my documents folder is often a good choice, although the operating system does add some extra junk along with your data (like my pictures and my music folders). Another good option is to install a separate hard disk or external drive to keep your data on.
