If this post does not make sense, just remember that you can not delete
from info gathered via CREATED/LASTMODIFIED, because
you will likely have former postdating later, that is because e.g. [same
file]
a restored backup on Jan04 has CREATED Jan04, but a LASTMODIFIED
from Jul03 will still have a Jan04 created.
In short write a log first, and decide on it.
Read your delete material documentation 'node' in and then.
And cross fingers you have a backup.
If you don't care, just exclude one folder from precaution.
That will be the one you lose over time , GUARANTEED.
