Problem: Personal geodatabase files increasing in size when edited with the ESRI OLE DB provider.
Repeatedly editing a personal geodatabase file with the ERSI OLE DB provider can cause the file to grow disproportionately in size.
This is a limitation of the Microsoft® Jet database engine.
Solution or Workaround
Compact the personal geodatabase .mdb file.
- Select the file in the Catalog Tree and right click on the object to bring up the context menu.
- From this menu, select Compact Database.
