Hello Vinay

When you get the value (e.g. via getValue method or the getClientData().AddedAttachment) of your attachment control in a rule, it'll return an array of attachments. Each item in the array is of type IAttachment. There's a property called contentType that allow you to check what type it is.

e.g.

// If you are calling this rule from the FormCell Attachment control's OnValueChange
// then the context will be the FormCell Attachment control itself. so 
// you can just call: let attachedFiles = context.getClientData().AddedAttachments;
// Otherwise find the control first in the current page first
// let myAttachementCtrl = context.evaluateTargetPathForAPI("#Control:MyAttachementCtrl");
// let attachedFiles = myAttachmentCtrl.getClientData().AddedAttachments

export default function uploadAttachment(context) { 
  // Get the added attachments
  let attachedFiles = context.getClientData().AddedAttachments;
  if (attachedFiles && attachedFiles.length > 0) {
    var len = attachedFiles.length;
    for (var i=0; i < len; i++) {
      var attachment = attachedFiles[I];
      // Do something with the content type
      // console.log(attachment.contentType);
    }
  }
}
