File names with version numbers...is it a good idea?

Question

I have this custom-made CSS reset stylesheet that I keep updating and I always mention the date and version number inside so I can keep track of multiple copies.

Is it a good idea to name my stylesheets using veersion numbers?
For example:

• example_v1.0.css
• example_v1.0.1.css

If it is, is it also a good idea for HTML, JS, and PHP files?

Answer 1

It IS a good idea to maintain multiple versions.

However it is not a good idea to maintain multiple versions manually. There are tools to do that, called source control/version control tools, and these tools provide features over and above just maintaining versions.

Some of them include Mercurial, Git, Subversion and CVS.

Answer 2

No!.. Even for small projects use svn!
