Completely remove WP8.1 storage-aware "temporary files"

Computer Store News: WP8.1 system has improved the original storage management, which is the newly added storage awareness. Through storage awareness we can view applications + games, music, videos, podcasts, photos, emails, systems, temporary Documents and other etc. So how can the temporary files here be completely removed?

Enter the phone settings ——storage awareness—— temporary files, we will find the total number of temporary files, click delete, the results found no effect.

WP Home User @茨末羽度 shared a way for us:

After entering the temporary file, even if the display is 0 bytes, then you need to delete the key each time. After the display is complete, continue to point, so point 4-5 times, check to see if it will be deleted. If there is no effect, you can restart your phone, and there will be obvious deletion effects.
