Eclipse taking forever to start

A couple times now, when I've started Eclipse (I'm using Eclipse neon), the startup screen is displayed for a very long time and Eclipse just doesn't start up.  To fix it, just delete the *.snap file.  (full path below)

The last time I was at my computer, it hadn't shut down properly.  It was the last day before the long weekend - Thanks giving weekend!  There I was, wearing my hat and coat, standing up at my desk, waiting for my computer to log out before I left.  I was jumping up and down, "come on, I'm late, I'm late, I'm late!" But the stupid thing would not log out, even though I had selected "Log out" or "shut down" a few times already.  So I was like "screw you, I have to pick up my kid," and I hit the power button.  Maybe not the best thing to do, but, sorry, I don't have a choice here. 

A few days later, here I am, and Eclipse won't start.  The solution?  Delete the .snap file.  It is located in:

workspace/.metadata/.plugins/org.eclipse.core.resources/*.snap

Delete that file, then Eclipse should actually start next time.  If that doesn't work, one time I found I also had to delete a few other .snap and .history files in

WORKSPACE/.metadata/.plugins/org.eclipse.core.resources/.projects/LAST_PROJ_BEFORE ECLIPSE_CRASHED

.
