Several of my favorites here, but a few suggestions.
File Utilities:
FilZip - Zip/Unzip program
www.filzip.com
TreeSize - Shows you what you are wasting all your disk space on
Jam Software's Tree Size
Programming/File Editors:
EditPad Lite - Free Notepad replacement that's what Notepad should have been. I bought the Pro version, but only after a few years of using the Lite version.

CSDiff - File diff program - compares and shows the differences between two text files, two directories of files, and has good reporting capabilities.
