How to move attachments to another folder?

[Blade_Runner]

I want to move some of my attachments to another folder. How can I move those files without broken links from the topic?

I do believe there is a setting somewhere in the ACP that lets you specify the attachment directory. Maybe server settings, I think?

Thank you for your prompt response.
I am using SMF 2.0 RC4. There is one setting where new attachment folders can be added. I know how to do that.
I need to know how to move some old attachments to the new folder.

You could move them then run repair_settings.php?
