This is my understanding of the files found in the Mail folder in the
Profile that is on the hard drive.
Each TB Account has a folder in the Mail folder that carries the name of
the account.
In each Account Folder there are three types of files.
FILENAME These files have no extension and contain the text of all
emails that are saved in that TB Account
FILENAME.msf These are the index/structure files that are used to keep
track of the text in FILENAME
NAME.sdb These are the subfolders you created in the TB Account. I have
create a subfolder in may TB Account called "Genealogy". There is a
file in that Account Folder called "Genealogy.sdb"
A fourth type will also be found in the Account Folder in the Profile.
these are *.dat files. I believe they contain data the defines the
folders, filters and other TB book keeping functions of the TB Account
The bottom line is if you are having problems with the *.sbd files there
is an error in one of the folders that has been created in the TB Folder
Pane for that TB Account. Try creating a temporary folder and moving the
emails in the problems folder to the temporary folder, and deleting the
problem folder. After you have check to see the problem files are gone,
you can move the emails form the temporary folder and remove it or
rename the temporary folder.
If you delete a FILENAME file, then the emails that were in the file are
lost.
If you delete the FILENAME.msf files they will be recreated when next
you open TB.
I have never tried to delete the *.sbd or the *.dat files so I don't
know what will happen.
