What is an ATT file?

An ATT file is a data file that may be created when information submitted through a web form is sent as an email attachment instead of being processed directly by a web server. These files often appear with names such as postdata.att and contain the data entered into the form by the user. The contents are typically stored as plain text or structured form data depending on how the form was configured.

More Information

ATT files are most commonly associated with older web form workflows that rely on email-based submission methods, such as mailto: actions or server-side email forwarding. When a form or server is configured incorrectly, or when the receiving system cannot process the submission as expected, the form data may be attached to an email instead of being displayed or stored normally. Web developers and administrators may encounter ATT files while diagnosing form submission behavior or maintaining legacy websites.

Although modern websites typically process form submissions using server-side applications or web APIs, ATT files can still appear in older systems or specialized workflows. Today, ATT files are are more commonly an indicator of legacy form handling or configuration issues than as an intended data exchange format.
