So I made a new git branch, did some things, added some files, tested some other things.
Decided I didn't want any of those changes so I committed on the new branch and then deleted it thinking that git would delete everything that was done in that new branch.
I switched back to my master and some of the files in the branch directory were still there.
The revisions of other files returned to their pre-branched state which is good but I am still left with a fair bit of folder garbage that is left over.
I tried doing a...
git reset --hard oldcommit
but that did not cause the files to be removed either.
How can I make git remove these files?
