How much storage to you need? I use SugarSync instead 5G of free storage to start with - I use it because it does this and two-way sync easily, no additional setup required.
Link here (we both get free storage, same deal as dbox): https://www.sugarsync.com/referral?rf=cvk5soqiyzjdt&utm_source=txemail&utm_medium=email&utm_campaign=referral
Not trying to spam, but damn, I can't believe how many dboxers are waiting for this when SugarSync is right here. I use both, personally.
