Recently came accross a legacy code which had a lot of css code and files, which was written over years and most of it was obsolete.

Downloading docx files as zip
Faced a weird issue with my new windows 7 laptop today. Whenever I downloaded a docx word document or pptx or xlsx it was getting saved as a zip file. The zip file had a lot of xml files.
