Several times now I've had Eclipse delete files for me seemingly randomly - then they appear under the 'Local History' option.
What is going on! I'm definitely not just deleting things by mistake.
Most recently it deleted my template files under html-template which are quite important!
I have an AIR project and a web project that references the src directory inside the AIR project. Usually I close one project while working on the other.
FYI: Currently my backup solution is Windows Home Server which means I have to go home to find a file if its lost in some other fashion and not in history. Yes I do plan to rectify that!
