Administrators with a properly-formatted .dat file containing the expressions can use this option.
Click Data Loss Prevention > Data Identifiers.
A list of data identifiers appears.

A message appears, indicating the status of the import.
Each expression contains a unique ID value. If an expression with the same ID already exists, PortalProtect overwrites the existing expression. If an expression with the same display name already exists, PortalProtect appends the suffix ”Original” to the preexisting expression and adds the new expression to the list.
