Saturday Mac riddles 97

Here are this weekend’s riddles to entertain you through whatever you’re now allowed to do.

1: Armour, letters, both messages and client.

2: Am I an aglet in the breeze, or the latest fashion in keyrings?

3: An outer cover or cloak, and a file system node.

I will post the answers first thing on Monday morning.

Please don’t post your answers as comments here: it spoils it for others.
