| Eseutil Mode | Switch | Description |
|---|---|---|
| Defragmentation | /D | Eseutil defragments the database files. This mode reduces the gross size on disk of the database (.edb) and streaming files (.stm) by discarding most empty pages and ad hoc indexes.For more information, see these topics:Eseutil /D Defragmentation Mode.aspx)How to Run Eseutil /D (Defragmentation).aspx) |
| Repair | /P | Eseutil repairs corrupt database pages in an offline database but discards any that can't be fixed. In repair mode, the Eseutil utility fixes individual tables but does not adjust the relationships between tables. ISInteg should be used to check logical relationships between tables.For more information, see these topics:Eseutil /P Repair Mode.aspx)How to Run Eseutil /P (Repair) in Different Scenarios.aspx) |
