That said, most of these have nothing to do with NSF. And you already have a lot of them installed by default. There's maybe 10 plugins I have installed myself, which you can discern by searching for "foo_" and comparing it to your list.
By this, do you mean searching on Google, or using another method?
Open foobar2000, click preferences, look at the list of plugins installed, and compare it to my list to see what you're missing, and what could be relevant to NSF files.
