This post is a bit off topic then usual. But if you are looking for an online storage account that can monitor windows or mac folders and keep them in sync with the cloud. Similar to that of DropBox then you should look into SugarSync.
SugarSync gives you 5GB of free storage compared too DropBox that is 3GB more and has plenty more features like streaming music photos videos right from SugarSync cloud to any mobile device way better than Dropbox.
I will post my referral link here if you all sign up for an account through my link you will receive an extra 500mb of storage and I will too.
If you are like me, most of my music resides on my laptop at home not my work PC. I listen too my music at work using SugarSync. So take a look at the website and if you like use my referral link https://www.sugarsync.com/referral?rf=ct4jxs3qa0cd9 we both receive more storage space.
