Why convert ATT to TXT?
A postdata.att file contains the field=value pairs submitted through an HTML form, stored as plain text. Renaming to .txt makes the file open automatically in default text apps without a file-association prompt and makes the nature of the file obvious to anyone who sees it.

- No conversion actually happens: the
.attfile is plain text internally; renaming or saving with a.txtextension changes only how the OS handles the file, not the content. - The
.attextension is also used by unrelated binary formats (Alphacam CAD/CAM tool definitions, Creatures game sprite data); those files cannot be opened as text. - A
postdata.attis typically a web-form submission packaged by a browser due to incorrect form encoding on the originating website - this is a site bug, not an issue with your computer.
