You can change an file's content type from its default to a more specific value.
You can only change the content type if your Alfresco administrator has configured content type properties so that you can enhance a file by giving it a type (for example, changing a standard document to a policy document).
- Click on a file to view it in the file preview screen.
In the Document Actions list click Change
The Change Type dialog box appears.
Select the required type.
Note: The New Type list is empty until types are defined by an Alfresco administrator.
When you give a file a type property it is shown on both the file preview screen and the Edit Properties screen for the file.
