Folders instead of packages after OS crashed

[Kubuntek]

Hi all!

While I was using Eclipse my operating system crashed. After I restarted my system I ran Eclipse again. But now, instead of packages in my src directory I have folders.
The problem is that now clicking on the class the options I had before like: refactoring etc. are no more available.

Does somebody now how to restore the view of packages in Eclipse.

Thx for help.

edit:
The problem is now solved.
After the crash Eclipse used Navigator view to show my project. I found the "package explorer" view which displays packages in the proper way view and now all works fine!
