From what I understand the system database is used to hold temporary tables, intermediate results and other temporary information.

On one of my database instances I have a tempdb that is seems very large (30GB). This database has not been modified (as in "last modified date" on the mdf file) in over a week. Is it normal to have the temp db remain that large for that long of a period? It seems to me that it should be updating fairly often and returning space that it is using fairly quickly...

Am I way off here or is SQL Server doing something weird?

FYI: This is a SharePoint 2010 database, not sure if that makes a difference.
