Makarand Mane on "[Plugin: W3 Total Cache] How to write files in Never minify the following JS files inbox"

I found solution in FAQ

Q : I'm not a hardcore developer, can you explain to me how this // and / stuff works and how I should specify the paths for CSS and JS files?<

Ans . You mean on the minify settings page right? Ok, it's simple:
// tells the plugin to search for the file with the provided path from the document root, e.g.: ///JS/jquery/jquery.JS
/ tells the plugin to search for the file with the provided path from the server root, e.g. //JS/jquery/jquery.JS

In most cases providing an absolute path is sufficient and most reliable. You can of course use relative paths, but we discourage it unless you really know what you are doing.
