Mass delete files/folders for File Management

[phpsns]

I really like the mass upload feature via Uploadify, but the other way around isn't easy. Hope there are options to delete more than one file using checkboxes (with option to select/unselect all). I see that the folder can't be deleted if there are contents in it, but it should display an option like "There are contents in the folder, are you sure?". Because it's really a pain to delete it one at a time without AJAX, so I have to use a FTP client instead by deleting the files from

data/upload

and also the duplicates for thumbs in

data/thumbs



Thank you!
