A. Yes, you can use the /t switch with the Eseutil utility to specify a local or remote location as the temporary folder to be used for the database to be defragmented. Using a remote location might slow down the defragmentation process, however. In the example below, I specified the Z drive, which maps to a network path (or you can use a UNC path), and a temporary file name for the database.

Note:                              It's recommended that you immediately perform a full backup                              of this database. If you restore a backup made before the                              defragmentation, the database will be rolled back to the state                              it was in at the time of that backup.
