Accidentally picked existing folder to sync to - Linux client removed all existing files

@sethj: Apologies for the trouble. I’d like to ask a few questions about your case:

  1. For the existing folder that you chose, did it have files that are also in Drive?
  2. When you added your account, did you only choose to sync specific files or did you sync all your files (step #4 here: How to get started with Insync)?
  3. Please check the folder /path/to/your/insync/folder/.insync-trash if the previous contents were moved there.
