Find all of the directories with a total size of at most 100000. /What
is the sum of the total sizes of those directories?/

Answer:
** --- Part Two ---
Now, you're ready to choose a directory to delete.

[[javascript:void(0);][Mastodon]]] this puzzle.
The total disk space available to the filesystem is =70000000=. To run
the update, you need unused space of at least =30000000=. You need to
find a directory you can delete that will /free up enough space/ to run
the update.
In the example above, the total size of the outermost directory (and
thus the total amount of used space) is =48381165=; this means that the
size of the /unused/ space must currently be =21618835=, which isn't
quite the =30000000= required by the update. Therefore, the update still
requires a directory with total size of at least =8381165= to be deleted
before it can run.
To achieve this, you have the following options:
- Delete directory =e=, which would increase unused space by =584=.
- Delete directory =a=, which would increase unused space by =94853=.
- Delete directory =d=, which would increase unused space by =24933642=.
- Delete directory =/=, which would increase unused space by =48381165=.
Directories =e= and =a= are both too small; deleting them would not free
up enough space. However, directories =d= and =/= are both big enough!
Between these, choose the /smallest/: =d=, increasing unused space by
=24933642=.
Find the smallest directory that, if deleted, would free up enough space
on the filesystem to run the update. /What is the total size of that
directory?/
Your puzzle answer was =7490863=.
Both parts of this puzzle are complete! They provide two gold stars: **
