I've been working on a project on Windows XP with IntelliJ 10.5.1. I 7-zip the project, unzip it and open it with IntelliJ 10.5.1 and all the sudden it can't resolve any of the classes. They all have the little 'j' icon on them. As soon as I open them up it seems to parse and index it. What has happened? I really don't want to go through hundreds of files opening them up just so that IntelliJ can re-save them in some format.
I've never touched the encoding settings. So, what should I do?
