In a way related to my thread "Script needed...", but in my case, I guess a little more complicated.
If you zip your text file(s), and upload it, then a shift-click on your link should open the default download application!
The same thing would generally happen if you use an .ext (using a binary data type) that has no viewer. But then after the download, the user would have to change it to open it up with his viewer.
Now if someone can come up with an answer for me!
