ZipContents

Find it on Package Control or GitHub.

ZipContents is a zip archive browser for Sublime Text written in Python. It allows you to view the contents of zip archives and open a contained file in a read-only text buffer.

At the time I wrote this, I had a number of completed customer projects whose git repositories were archived on premise in zip files for regulatory compliance. It was frustrating to have to extract an entire archive every time I needed a quick glance at a source file for reference, and the only ST package with similar functionality was unavailable due to link rot. So I wrote and open-sourced my own!
