Hi Terry:

Truncating the log does not free up disk space. It only frees up space from within the log file so that transactions can be written without having the file size growing.

If you want to reduce the size of the transaction log file, use DBCC SHRINKFILE or DBCC SHRINKDATABASE. You can use DBCC SHRINKFILE to shrink the transaction log file only. Tons of information about these commands can be found in SQL Books Online.

thanks...
