TROPE HUNT Week 5 Day 2 (Patreon)

Did you solve yesterday's clue? If not, here is the extra-long riddle you might have found:

And the Trope Hunt ends!
(It’s the penultimate day.)
Seek out One Last File.

And a final hint:
If right now it is Monday,
Try again Tuesday.

It’s great to see you
Found your way back here again.
Spring is for cleaning.

Happy Hunting!
