FossaMail profile migration tool

This tool will help you transfer your Thunderbird profile (addresses, accounts, emails) from Mozilla Thunderbird to FossaMail. It is a simple tool and doesn't have much in terms of advanced features, but should give you a quick and easy way to copy your data from Thunderbird into FossaMail.
This tool may not work for everyone, since it has a few important limitations:
  1. This tool only works for the default profile location for Thunderbird and FossaMail (not for custom profile locations)
  2. This tool will not copy mailboxes that are stored outside of your main profile folder
It was put together mainly for people who have standard installations and/or who do not have enough knowledge of the Windows O.S. and filesystem to manually copy the profiles. It is not meant to be very versatile or flexible, but "gets the job done" in most cases.

Please close Thunderbird and FossaMail before attempting to copy your profiles. Not doing so may cause an incomplete copy, corrupt data or give errors.
