I'm done with this. If someone wants to maintain it send me a note and I'll transfer the repo. Or just fork it, or whatever.
- Navigate to your
/local/plugins
directory (create it if it doesn't exist) git clone https://github.com/chimo/gs-fileManager.git FileManager
Tell /config.php
to use it:
addPlugin('FileManager');
A new "File Manager" link should appear in the left-navigation on the "Admin" page.
On the "File Manager" page, you should see a list of files saved on your instance, and their total disk space usage.
