[Deleted all my photos on accident]

About 5 years worth.

It was syncing to the computer, I deleted the placeholder photos when it was only synced up to 10 photos.

Then I notice the all the photos on my phone were gone.

I recovered the placeholders, did not restore phone photos.

I went into the .sync folder for the archive but there is no archive folder.

Is there anything else I can do?

[How do I sync only new files?]

I have a bunch of old photos but I only want to sync new photos I take.

Is this possible?
