## Importing Expressions

Use this option if you have a properly-formatted `.dat` file containing the expressions. You can generate the file by exporting the expressions from either the ScanMail server you are currently accessing 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, informing you if the import was successful.

   | ##### 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 pre-existing expression and adds the new expression to the list.
