For those who are already using version 1.03 or earlier : I added a little utility that moves some files from 1.02 format to the newer 1.03 format. you'll have to copy this file (102to103) to the maildirectory. The files : mailbox.dat address.dat singlbox.dat are already in this directory. copy the utility 102to103.exe to the same directory and execute it. (Of course you already made a backup so it is not necessary to say to make one since you always make backups before installing new software don't you ?) The 102to103.exe copies the original files to the files with extension old and creates three new files with the same extension as the original files had. If you plan to use 1.04 and already have 1.02 (or used the 102to103 utility) then use the 103to104 utility for upgrading to version 1.04. 103to104.exe is the same kind of utility as 102to103 is, but then of course to port from version 1.03 to 1.04.
