You can configure a database to automatically shrink by setting the autoshrink threshold option in connection string. Shrink does not create a temporary database file.</p> <p>From <a href="http://msdn.microsoft.com/en-us/library/system.data.sqlserverce.sqlceengine.compact.aspx" rel="nofollow noreferrer">SqlCeEngine.Compact documentation</a>:</p> <p>Reclaims wasted space in the database by creating a new database file from the existing file. By creating a new database means, it reclaims the free space between rows. </p> <p>To be more clear, Shrink claims the pages which are entirely free or unallocated; where as, Compact claims the wasted space with in the page too. Hence Compact requires creating a new database file. </p> <p>Empty space with in the page could be as result of:</p> <p>1) If there were 5 rows in a page and two of them are deleted</p> <p>2) If there was a row in the middle of the page which on update required more space, has moved out of the page (Ex: nvarchar column update)</p> <p>Empty pages and unallocated pages could remain in database as a result of:</p> <p>1) All rows in a page are deleted</p> <p>2) Whole table is dropped</p> </blockquote>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
