And a whole swag of others through the years, many of which I still use on the odd occasion, even some of those I have listed only get used on odd occasions. Some like CD/DVD/Blu-ray burning or ripping I rarely do now.
Many of my own creations are used in quite a few of the above categories, as supplementary, but especially related to ebooks and games and music. Often my programs are frontends (GUI) for command-line programs (such as gogcli.exe by Magnitus for downloading GOG games, as well as cataloging assistance).
