Downloading my previous returns is not working?

When I try downloading my previous years tax return for a CRA dispute it only downloads as " .file " instead of a PDF as it says that it is. So far the " .file " is useless and cannot be viewed properly.

Actually turns out if you just rename the file adding " .pdf " to the end of it the file converts.
