Library Cache Error

Sometimes Unity does not fill me with confidence…

I posted about some errors I’ve been getting here:
http://forum.unity3d.com/threads/93132-Import-Errors-When-Opening-On-Windows

This morning I got something different. I launched my project, got the errors I usually get (from above post), then got the error shown in the screenshot below. “Try Again” and “Cancel” wouldn’t do anything so I went to “Force Quit”. I relaunched Unity, and got exactly the same thing (plus some panic). Then I relaunched a third time and the project opened without issues.

Does anyone know what this error was all about and whether or not I should be doing anything to prevent it in future? It’s kinda odd that it says the operation completed successfully… was that the operation to make me poo my pants?

that error normally means the folder was used by something else and thus file access failed.

Agressive security programs can cause it or having the project folder in the drop box folder can easily cause it too.

If you don’t have the project folder IN the Dropbox folder, what’s the alternative if you plan to use Dropbox?

Thanks for the security tip. I’m running a McAfee product so I might look at excluding the Unity projects path to see if that helps out.
