Drupal has its built-in text editor. With this module you can add a button in your text to display files as a link, after uploading.
So you do not have to upload the files with FTP and then search for the link. This all happens in one step. With IMCE you can do this too, but this is easier.
This button must be set up with the word processor.
Use the button:
A link will appear in your text. The file is downloaded.
