You do NOT need to run this (I already did), but you might be interested in this SQL to shrink transaction logs. You do need to do a backup of the databases after you truncate them (I'm not concerned since these old databases are lookup only - no new data should be written to them).
USE MASTER GO BACKUP LOG file WITH TRUNCATE_ONLY GO USE db GO DBCC SHRINKFILE ( 'dbfile' ) GO USE Master GO
I used the following code to generate the list of files in the database.
SELECT 'SELECT name from ' + rtrim ( name ) + '..sysfiles' FROM sysdatabases WHERE name LIKE 'dbfile%' ORDER BY name
Don't forget to back-up the database once you're finished as well. A FULL database backup should be done!
