I came here looking for a solution since each of my folders have like 3k+ files in it, i've alreaddy tweaked my memmory to 1024MB and execution tom 360s in php.ini and cant have a full directory list.
So i want to make a suggestion:
Pagination, as in post list. Is it possible to have pages in diretory list? It would solve 50% of importing problems.
by the way, great plugin!
