The first step in setting up the “File Attachment” control is to create a string attribute (Nvarchar, varchar, …) to store the data in the entity associated with the form containing the control. Refer to section 9 for information about entities.
Note: The default location for storing the attached form of the form is in the Dms folder in the installation path of the application, which can be changed during the installation of the application.
By clicking on the entity name and choosing the “Add New Filed (See 9.3)” option, the attribute will be created and the type of attribute can be changed in the edit box
