I'm using Eclipse for Java development. All my sources compile fine and the resulting application compiles fine. However, I keep getting an "red-x" error notification in the Package Explorer.  All my sources in this source directory (too long for the snapshot) compile fine, none of the show the "red-x" error icon.  Any suggestions on how to fix the problem would be highly appreciated.

So I've been cleaning up my desktop for the last few minutes, and I tried to delete this empty folder, but it has some 3.46GB of data in it? And I'm like wtf is going on. Any ideas of why this is happening? I restarted my computer, thinking it was just some kind of fluke, but it is still happening.

If there is a file and the filename starts with a dot, does that mean you created the file and you are hiding stuff in it, or can the files get created on their own without you creating the filename?
