The ZipFileCreator service now recursively zips folders. Files App doesn't need to enumerate all the files in folders to zip anymore. This is done in a much more efficient way by ZipFileCreator. When zipping a folder containing 100 subfolders with 1000 small files each (for a total of 100,000 small files) on a kevin device, the old system takes 144 seconds (listing files 103 seconds + zipping files 41 seconds), whereas the new system takes only 26 seconds. This is an improvement by a factor of 5.5.
