The current interface allows to enter a limited number of file extensions, and only files with any of these extensions can be uploaded.

For many purposes this is nonsense. In many applications a limitation by file extension renders Drupal unusable altogether, due to this brain-dead design.

Possible alternatives, each of which would solve the problem:

  • Preferred solution: Remove the file extension limitation altogether. Few people need it in its current form.
  • Change its meaning such that the listed extensions are prohibited, rather than allowed.
  • Allow the user to enter just one asterisk, meaning that all file types are allowed.
  • Add a checkbox that either disables this function or changes its meaning, as described above.
