Looking to manage the files on my home network from my iPad but need the ability to access files on my NAS (samba shares) and ideally also have Dropbox support. Other cloud services are a bonus but Dropbox is my preferred service at the moment. I have seen a couple of apps that may do what I need but they offer no lite version for testing out and some are relatively expensive. Main uses will be copying files from laptop to NAS, moving/deleting files on my NAS and copying files from laptop/NAS to Dropbox. Any recommendations?
