Subject: Which is more expensive Rename or Move?

Hello,

I'd like to create a ruby script that parses emails(that will grow with
volume) and I need to find a way to distinct which emails the script
touches. I can either rename the email after the script is done with it
or move it to another directory. Which would be a least costly operation
or are they both equal expensive?

Would you have any other suggestions for this problem?

The way I understand it is that when you rename or change directory you
are just changing the path. I will be using a linux box(ubuntu) and I
think the directories are stored in a tree structure in which rename
would be less expensive.

Thank you
