That's the purpose of implementing this API i.e to get the file attachment component attributes. In the case at hand, you can set an alert/warning for the user to re-upload the file with the expected name.

Any further implementation (resetting/deleting the value of the component) has to be taken care of using javascript.

OOTB, the file attachment component does not support attaching files with a filename starting with characters (.), containing characters \ / : * ? " < > | ; % $.

Otherwise, you can configure a check with getFileAttachmentsInfo as below:

guideBridge.getFileAttachmentsInfo({
    success: function (list) {
 //some specific file names that are supported     
            } else 
            if (fileName.match(/["add the special character here"]/)) {
              alert("File name cannot contain a special character.");
            }
});

Hope this helps!

    @pulkit_jain_ ,

    guideBridge.getFileAttachmentsInfo({
    success: function (list) {
 //some specific file names that are supported     
            } else 
            if (fileName.match(/["add the special character here"]/)) {
              alert("File name cannot contain a special character.");
            }
});

     

    Above code only give the file info like name and path of the file but we are not able to avoid the upload how we can achive the uploading file

        @manikanthar1295 This is certainly possible, using 

        getFileAttachmentsInfo

        You will have to implement logic to delete the uploaded file in case of regex failure.

            @manikanthar1295 If it's client-side then you should rather prompt the user with a warning and ask him to reupload the file with the correct pattern.
