I am using SugarCRM where it creates cache files (.js and .css). The issue is it returns 0 as the size for most of the cache files stored in disk when we see in Firebug.

Data Size 0
Fetch Count 4
Device disk
But when I type the same URL in new tab in browser window, it shows the contents correctly.
This reason the website is not loading the css and js.
I tried to clear the cache in local system using browser still no use.
You should delete the cache directory in SugarCRM server after you make any changes or alternatively you can repair which will restore the things.
It should solve your issue
