Custom Form - add attachement section

Hello Sandesh,
 
I'm afraid that Zendesk does not offer a native feature to selectively edit or reject specific types of attachments for incoming tickets. In its default configuration, Zendesk generally permits a variety of file types to be attached to tickets without extensive filtering or restriction.
 
If you have the need to restrict or manage certain attachment types, you would typically need to explore solutions beyond Zendesk's core functionality. This may involve implementing custom processes, leveraging third-party tools, or engaging in custom software development to meet your specific requirements.
 
In essence, while Zendesk provides a solid foundation for managing customer support interactions, customizing attachment handling to reject specific types would likely involve external processes and tools. These adaptations can help align Zendesk with your organization's attachment management policies and security needs. Always keep in mind that Zendesk's features and capabilities may evolve, so it's advisable to stay informed about any new developments or features in this area.
