Search options and ability to delete on mass from search results

Hi there

It would be good to be able to delete on mass from a search result via the interface.

For example, I would like to be able to search for all files that have not been served or accessed in over 4 years and remove them from the server. I believe that most of my storage use is redundant and no longer required.

Also being able to filter on date, file type, uploaded file name etc would help make it easier to locate files that I am looking for.
