...i also need clearification on these whether we can change the file name or not....
Well, of course you can change the file name. You can also completely remove it. The follow up question is: What do you expect to happen once you do? Should Liferay still work? Do you just want to change it or do you want to know what happens when you do?
If you just rename the file, Liferay won't work. You'd need to configure in Liferay, which file to read instead. What do you need to change in order to make it work? Who cares? Why you might want to do this is completely beyond me. In my wildest dreams I can't think of a usecase that involves changing a filename of a file internal to Liferay's implementation. Whatever problem this is supposed to solve, renaming that file is probably the wrong solution for it.
