Eclipse History for non java files

I noticed that not all file types end up in Eclipse history. Is there a way to edit the preferences so that all file types get the history treatment? *.js, *.jsp, *.xhtml, *.css...

EDIT: I since had many instances of history not being saved correctly. In this example, it was a java file that i made quick m开发者_Go百科odifications

Hm, can you double-check? In Eclipse Helios, I can create e.g. a text file in a Java project and it is correctly tracked by the History mechanism.
