Question

How can I decrease the size of my personal geodatabase after validating it?

Answer

After validating a topology in a personal geodatabase, the size of the .mdb file that the geodatabase is stored in may have increased due to the number of updates performed during the validate process. The Compact Geodatabase command in ArcCatalog can be used to decrease the size of the personal geodatabase. The command can be accessed by right-clicking on the personal geodatabase.
