Correct the attachment file upload size in Nintex Forms
For attachment size limit for list items on upload forms designed by NF2013, it doesn't show correct value for the attachment upload size.
By default in SharePoint 2013, attachment size limit of list item is equal to 50 mb. When web application level document upload size limit is set to 2 gb. It does not mean attachment size is also 2 gb. To increase attachment limit size of list items there are 2 obligation. One of them increasing document upload size limit in Central Administration(this is already 2 gb in teamspace). But this is not enough to upload attachment over than 50 mb. At the same time you have to change some settings(maxRequestLength, executiontimeout…) in the web.config file of web application.
Current in list attachment upload form designed by Nintex Form, it shows file size value only referencing the Maximum Upload Size field set for the web application level within Central Administration. But in SharePoint the attachment upload size is also refer to web.config file, the attachment control is not referencing this setting actually. We cannot manually change the message for the attachment control to correct the file size value.
We think it's a bug in NF which should be fixed to avoid confusing from user side.

If you feel this is a defect, please contact support@nintex.com

Does this mean that in SP2013 Nintex forms, we cannot upload any files larger than 50 MB??
