What's the best app for uploading/downloading files to my network drive? I have a linksys e4200 v1 on the latest firmware with a wd mybook essentials hooked up to it with the USB port. My router has FTP settings for the storage drive and is also upnp and Dlna comparable. I'm looking for a way to upload and download files to it from my Idevices and also stream videos, music, and photos from it and dl said media files if I so choose. Heavily considering getting something like the wd mybook live so I can have web access to the network drive. What are your experiences with network storage, NAS', upnp/dlna, web accessible NAS with the ipad?
