File management API method

In my efforts to 'find' the excessive blob storage I have discovered that there are many blobs associated to files which are no longer linked to Resources.

There is currently no way of finding these Resource Files as their File Ids are not stored anywhere. My workaround is search for every integer value - incredibly inefficient.

I wish for a method to return a list of all existing Resource Files.

List<ResourceFile> GetAllResourceFiles()

I can parse this result, recognise redundant files and delete them.

Thanks
