How to get Arduino to save library file edits?

Hello,

I am working on something which requires to me to edit a library. I open up my sketch, then "add" the .h file i need to edit. I make the edits, but when i press save, the library file isn't modified?

IS there an simple fix to this, editing the libray files in notepad is irritating because it's not formatted.

Thanks

library files need to be updated outside the IDE as they are treated read only.

I use NOtepad++ for that as it has a pretty good syntax highlighting

Thanks, I'm familiar with note++. I just didn't think about it.
