There are some useful plug-ins for Notepad++ at http://sourceforge.net/apps/mediawiki/notepad-plus/index.php?title=Plugin_Central
These plug-ins include a hex editor and other useful tools. One tool that I especially like is to ability to run the current file. This is very useful when working on batch files.
For burning CD and DVD, I have found CDBurnerXP from http://cdburnerxp.se/en/download to be very useful.
The features are listed at: http://cdburnerxp.se/en/features
The price is excellent - FREE!
