Explanation:
How to: Shrink a Database This topic describes how to shrink a database by using Object Explorer in
SQL Server Management Studio. The database cannot be made smaller than the minimum size of the
database. The minimum size is the size specified when the database was originally created, or the
last explicit size set by using a file-size-changing operation, such as DBCC SHRINKFILE. For example, if
a database was originally created with a size of 10 MB and grew to 100 MB, the smallest size the
database could be reduced to is 10 MB, even if all the data in the database has been deleted. To
shrink a database
1. In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand
that instance.
2. Expand Databases, and then right-click the database that you want to shrink.
3. Point to Tasks, point to Shrink, and then click Database.
4. Optionally, select the Reorganize files before releasing unused space check box. If selected, a
value must be specified for Maximum free space in files after shrinking . Selecting this option is the
same as specifying a target_percent value when executing DBCC SHRINKDATABASE. Clearing this
option is the same as executing DBCC SHRINKDATABASE using the TRUNCATEONLY option.
TRUNCATEONLY shrinks the file to the last allocated extent. This reduces the file size without moving
any data. By default, the option is cleared.
5. Enter the maximum percentage of free space to be left in the database files after the database has
been shrunk. Permissible values are between 0 and 99. This option is only available when Reorganize
files before releasing unused space is selected.
6. Click OK.
