where are the sql server log located
By default, the directory where all database files and transaction log files are located is \Program Files\Microsoft SQL Server\Mssql.1\Mssql\Data. When you run SQL Server Setup, you can specify a different location as the default location for data files. The data file location is the root directory where Setup creates the folders that contain database and log files, in addition to directories for the System log, back-up, and replication data.
