CloseReview for Folder Account by Sean C
Rated 5 out of 5 stars
Thanks to FTL for the instructions. I was unable to make it work on Windows XP PC (xpi was reported as "corrupted" by TB), but was able to do it on Linux CentOS server using unzip and zip utilities.
Thought this might help others who may be having trouble.
