title: Intellij IDEA red/brown highlighted file name
body: <p>I am using Intellij IDEA 12.1.6. Some of the top level or functional files names are in brick red text. For example, the manifest file and the .iml file. I am concerned about the iml file, because that is the project file.</p>
  
  <p>IDEA documentation says that it "highlights" text in red if there is a merge conflict in the file, however, when I open the iml file, there is no merge conflict in it. Also, the text is in red, it is not highlighted, although it is possible that by "highlighted" they mean the color of the text.</p>
  
  <p>Why would the text of the file name be in red? Screenshot is below:</p>
