J2e shared files area:
Hover over the left hand side of each file icon – a square should appear which you can then click on to “tick”/select the file – hover over all of the files and “select” all of the files you want to remove from the shared files area, just like I have below. Alternatively, to select all the files right click on a file, and select "select all":
Select the “private” option – this will change all of the selected files to “private”.
Then, click the blue ‘x’ which will stop the files being shared with the school. The original files will still exist in the ‘my files’ area for whichever member of staff originally created the file.
Next time you click on ‘Shared files’ you should see that all of the files have now disappeared.
