## Importing Expressions

Administrators with a properly-formatted `.dat` file containing the expressions can use this option. Generate the file by exporting the expressions from either the ScanMail server on the current server or from another ScanMail server.

### Procedure

1. On the left navigation bar, click Data Loss Prevention → Data Identifiers.
   A list of data identifiers appears.
2. Click the Expressions tab.
3. Click Import and then locate the `.dat` file containing the expressions.
4. Click Open.
   A message appears, indicating the status of the import.

   | ##### Note Each expression contains a unique ID value. If an expression with the same ID already exists, ScanMail overwrites the existing expression. If an expression with the same display name already exists, ScanMail appends the suffix “Original” to the preexisting expression and adds the new expression to the list.
