If you're on <=9.2 and install it as a CIA or something, then yes. But supposedly it's REALLY slow.
TL;DR: yes.

It's certainly a little faster than FTP though. The fastest I've seen it go was 500-600KBps, but I agree, its kinda not worth setting up.
I'd just stick to ejecting the SD card.
you are quicker with just removing the sd connect it to pc, do your thing, remove it from pc and place it back into your 2ds.
