I see that you can set up "Syncing" with Skydrive, with a little bit of setup work. here's a ling that tells more about that;
Windows Live Skydrive has been featured on MUO, (the "MakeUSeOf" web site), as one of the best services to come out of Microsoft for offering 25GB of online storage. Not only can you use it as a Picasa or Flickr alternative thanks to its integration with Windows Live Photos, but with a little preparation, you can also map it as a network drive (see SkyDrive in Windows Explorer) so you can use it as a file storing, syncing and sharing service.
I hope that gets you started.
Is it possible to initially upload a file (or files; folders) to a SkyDrive account (this I have already done) but then have those files automatically sync as the original file on my computer changes? It seems that I must re-upload any changed file - cumbersome, time/resource wasteful and I'm sure I'm bound to forget one of the critical files that needs to be synced!
I tried a third-party product from Gladinet but it failed in this task so I stopped using it.
I'd be grateful of any suggestions or even just a comment that explains why it can NOT be done.
