Event 1056 - File Name Restriction

Applies To: Windows 7, Windows Vista

Windows® Internet Explorer® 8 form submission has been changed so that the file upload control (input type=file) only submits the file path to the server. Previously, the full path was sent to the server. In addition, programmatic access to the value property of the file upload control will also remove the file path information from the file name. This means that Internet and Restricted sites do not show the file path, returning only the filename portion of the specified file path.

When Is This Event Logged?

This event is logged when the file path is replaced with the file name.


For more information and examples, see the Event 1056-File Name Restriction topic from Internet Explorer Application Compatibility.


There is no workaround for this feature and it may not be turned off. Removing access to the full file path of the file (for Internet and Restricted sites) is a security measure that helps to prevent potentially malicious sites from accessing information that can be exploited.
