Yes, just drag and drop right in that folder. I left my phone sit for maybe 15 minutes before I checked it again and when I did, it was all merged into a full Zoe
That doesnt work for backing up and restoring though. Basically I was looking to do 2 things with this. One is sharing a Zoe between 2 HTC Ones, but I wanted both phones to have a full Zoe that they can edit as if it was taken on that phone. For example, Phone A takes a Zoe. Then its copied to Phone B. Phone B can then view it as a normal Zoe, use all the cool editing tricks and all. Sharing through the web does not allow that. The 2nd was just for pure backup reasons. At some point, you will run out of room, which means you will then need to back them up on your computer or a DVD, or however you archive media. Lets say, 2 months later, you decide you want one of those Zoe put back on the phone. This of course isnt even possible with web sharing, and on top of that, up until this morning, I found no way to get the full Zoe experience back. Luckily the phone is smart enough to recognize those stills and mp4 are pieces of a whole. So looks like backing up or sharing will not be an issue.
For friends that do not have the HTC One, the web sharing at that poing is useful though. I do like that feature. Just didnt solve the problem I was looking to figure out.
