Configuration: Storage Options

• Use this configuration option to customize the path for the temporary files of the following directories:

  • System
  • Configuration
  • Databases/{database_name}

• By default, the temporary files are created under the Temp folder in those directories.

• When the Storage.TempPath is configured:

  • The System temporary files will be written to "<Storage.TempPath>/System".
  • The Databases temporary files will be written to "<Storage.TempPath>/Databases/{database-name}".
  • The Configuration temporary files will be written to "<Storage.TempPath>/Databases/{database-name}/Configuration".

• To specify a different path for the indexes temporary files go to Indexing.TempPath.
