There is nothing illegal about selling or giving away vinyl records unless you keep copies, at which point you aren't really selling/giving them away - you're selling/giving away a copy, albeit your original copy. What is so difficult to understand about that?

This argument used to crop up regularly when people made cassette copies to play in the car. Perfectly legal if you keep the original, otherwise it's a breach of copyright.

Okay, make light of breaking the law if you must - the likelihood of being prosecuted is quite low, so you'll probably get away with it anyway.

Anyway, I would never get rid of any of my vinyl... too many memories.

'Read only' stops you accidentally deleting or overwriting the folder (and optionally its contents) unless you are really stupid and ignore the warning messages that tell you what you are trying to do! It's not limited to folders - you can do it with individual files, selections of files and even selections of folders.
