File Manager Plugin For WordPress

Hello Everyone here, I really need help with this issue, if anyone could help you would be a lifesaver.

Coders, Developers and WP experts I need your help!

I am using a plugin on my WPMU install called ‘File Manager plugin for WordPress’ from themeforest here-

I need to know how I can get the plugin when it is activated to automatically create a folder with a random name under the ‘wp-content/uploads’ dir for each site in the wpmu install it is activated on. And then it uses that directory automatically for folder where it grabs the files from on the file-manager???

Please look at how the plugin works.. just for info I have bought this plugin through themeforest already.
