We've created a new file manager that will give all members more control over all the files they have loaded to their sites. The new file manager will also allow you to manage the amount of storage space you use. If there are older files that you loaded once upon a time that you no longer need, you easily delete them.
Check out the new file manager by clicking the "file manager" link under ADVANCED FEATURES in your control panel.
As always, your comments are most welcomed.
