An administrator can manage file types in Administration/File Types menu.
All Files in PIM can be divided into types. And you can create variants of these types and validation rules for them yourself. The type field is optional. One File can have only one type. By default, the following types are added to PIM: Presentation, Graphics, Archive, Video, Audio, Icon, Image, Spreadsheet, Document and File. You can create new types, change the validation rules or priority for existing types, or delete them.
To create a new file type, go to Administration > File Types
and click the Create File Type
button
To add validation rules to a type, click the +
button in the corresponding panel. Select the validation type and set the necessary parameters.
If "Assign automatically" checkbox is checked, the system will check automatically, if a newly uploaded files can receive this file type automatically, provided the validation rules for this file are complied with.
