Replacement for deprecated AssetsService Im developing my first plugin and was interested in using the findFolder() method from AssetsService but i noticed the class is depreciated. What is the proper way of achieiving the functionality of findFolder() without using the deprecated class? TIA!
Most of the Assets related classes in Craft 2 have been deprecated because they've been completely re-written/refactored/removed for the upcoming Craft 3.

So if you're looking for a Craft 2 replacement, there isn't one... the replacements are in Craft 3.
