Eran, you really want to learn to use svn. Seriously, you do yourself a favour, greater than you can possibly imagine.
I have been programming without revision control for many years, and sure enough, you can do that. Occasionally you will spend an afternoon trying to undo the changes of yesterday because they don't work, and occasionally you will be searching for your backup disks in cold sweat, and sometimes you will be asking yourself when you changed a particular file, and why. But yes, it mostly works.
A revision control system such as svn makes your life a lot happier and easier by taking all these problems out of your hands (it also makes merging easier). As an allegory, think of crossing the Atlantic Ocean. You can do that in a canoo, or you can fly in a jet. Both methods work, most of the time
If you use TortoiseSVN (tortoisesvn.tigris.org) then doing revision control is as easy as a right-click on a folder.
A good introduction about revision control (in particular svn) works can be found here:
