We have been using 1.8 up to this point.  In 1.8 you had a file folder that you could see your files and organize them into folders etc.  Or if you were upload say a Capitivate file that you have to ZIP upload unzip and then choose the file.....how do you do that in 2.4. We have teachers that upload their grading keys to Moodle so they always have them with them that they can go in and open. Hope this makes sense...
