Ever since I switched to windows phone I've sorely missed having an official dropbox app. Recently I've toyed with the idea of moving all my crucial files to OneDrive instead. I have more storage on OneDrive and the WP OneDrive integration is very handy.

I'm thinking about having both cloud sync services point to the same local folder for the first few weeks. That way if I want to go back its an easy task (and I can keep using dropbox's superior public folder)

Has anyone else done this? Are there any potential issues (permissions, conflicts etc)

I see no reason pointing Dropbox to a folder called A service formally known as Skydrive instead of Dropbox would cause a problem. –  Ramhound Aug 13 '13 at 11:25
I'm just thinking two cloud based apps will be syncing the folder. I wonder will they interfere with each other or cause any latency or locking issues –  roryok Aug 13 '13 at 16:52
To my knowlege neither Dropbox or The service formally known as Skydrive uses local files ( within their syncing directory itself ) to handle the syncing process. Please note the Skydrive is quickly changing how it works, Windows 8.1 provides native support, and currently the location cannot be changed. –  Ramhound Aug 13 '13 at 17:23
Thanks ramhound. The dropbox location can be changed so I'll probably point that to the SkyDrive folder –  roryok Aug 13 '13 at 21:52
Actually it turns out that I can only place the dropbox folder within Skydrive, which is not what I wanted. =( –  roryok Aug 23 '13 at 9:55

I have done some tests with sharing the same folder on different clouds (One Cloud, Google, dropbox,...)lately. To be honest, it seems to give nothing but problems. In fact, the files seem to be in 'sync mode' all the time and the services take a lot of memory resources. I think the reason is the following: one cloud (f.ex. dropbox) sees a new file and starts synchronising. Once done, it seems that something on the folder or file is modified. The other cloud starts syncing as well. Once done, dropbox sees a change in the file and resyncs. But so does the other cloud when dropbox has synced. So both clouds seem to be syncing all the time.

This is likely to be highly OS-dependent. The inotify syscall in recent-ish linux kernels, for instance, allows listening for modification vs access without locking issues; and I would guess any cloud client would be using the right ones. –  tucuxi Oct 25 '13 at 9:30

Cloud services will always timestamp their synch folder on your device with the time of their last synchronisation. How exactly they do this may vary from service to service.

If the synch folder is shared between services, the second service will see the date change of the first service as an update and will then go off and try to synchronise.

This can get you into a deadly embrace situation where everything is synchronising all the time.

I find it easier to have a daily run of robocopy (on Windows) to synchronise the two local synch folders. That does mean that you have two copies of everything on your local system but I have put each service's synch folder on a separate local hard drive so there is additional redundancy.

I haven't tried this on a phone so can't say if this is feasible there.

yeah robocopy seems like a better solution, although maybe more often than once a day (on the hour maybe?) Not sure what you mean about trying on a phone as we're talking about desktop clients! –  roryok Oct 25 '13 at 10:40
ah, yes, I see how that's confusing. I just wanted to shift priority to SkyDrive on the desktop to match up with the phone, as I mostly use Dropbox at the moment –  roryok Oct 25 '13 at 10:46

This is not possible. OneDrive (as of Oct 2014) always creates a sub-folder called OneDrive inside the folder you select. The best you can do is create a folder called OneDrive inside your DropBox folder, or vice versa.
