I tried turning on NFC and touching the phones, but I didn't see any way to transfer the folders.. Same for Bluetooth..
Sent from my Nexus 5 using XDA Premium 4 mobile app
Upload it to an online storage (Google drive, dropbox, box, etc.) and send her a link.
Or there are probably some apps in the play store that will transfer files over WiFi.
Folders and files can't be sent with NFC. It's mainly for smaller things like photos, links and contact info.
