Taking Ownership
I had a folder that would not let me (the administrator!) throw it away locally because it was owned by someone else. I think this was because it was created remotely on Jupiter or BlueMac. I could not change the permissions locally and was stumped until I found this article that said I would have to "take ownership", then change permissions, then toss it. Worked.
