I also formatted the wrong drive once, thought i lost everything, i also thought my world had ended. Fortunately i backed up to dropbox, but as dropbox is a live folder id wiped that to!! NOOOO, thankfully dropbox has a "recycle bin"
I quickly pulled it out of bin and restored it! Really is worth moving over to Cleaner Planner now, im a massive fan of WCP, its been great for me, but it can be a little unstable and sadly support seems to have fallen away.
Cleaner Planner is great. Very happy with it.
