Deleted already existing recipe folder

Upon installing the cookbook app, it had deleted all my recipes that I was already saving in a folder called, you guessed it, Recipes. Fortunately, I have a backup, but might be nice to have a warning. I didn't get any warning, nor notification. Just all my recipes... gone.
Looking a little deeper, it shows empty Recipes folder from the web page. My Android phone still shows my recipes, but I'm assuming that's because I've got them sync'd to the device. I just tried syncing from the phone, but it doesn't appear to do anything. Most of my recipes are printed pdfs from web pages, if it matters.

Start by reproducing installation with an existing Recipes folder, then compare the web page with the Android app after synchronization. Trace the installation and sync entry points to determine when the folder is removed and whether the behavior is recoverable. Done means existing recipes are preserved and the user receives a warning or notification before any destructive action.
