I copy the entire Thunderbird directory. Are the colors stored in the registry?

This review is for a previous version of the add-on (1.0). 

Colors are stored in .msf files.
Thunderbird portable might overwrite .msf files when it detected mbox files updated. Let me look at that when I have time in a few weeks time.

Love the app - great idea and well implemented. I have run into a problem though: I use Thunderbird Portable V5.0 and for some reason the folder color settings do not transfer when I copy my Thunderbird folder to a new computer. All my accounts are set up as IMAP. Aside from that, works like a charm.

Do you also copy .msf files?
