title: IntelliJ IDEA adding numbers to project name
body: <p>When I "Create a new project from existing sources" in IntelliJ IDEA, it adds <code>_####</code> to the end of the project name, where <code>####</code> is a seemingly random 4-digit number.</p>
  
  <p>This happens with this version:</p>
  
  <pre><code>IntelliJ IDEA 2018.1.5 (Community Edition)
  Build #IC-181.5281.24, built on June 12, 2018
  JRE: 1.8.0_152-release-1136-b39 x86_64
  JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
  macOS 10.13.5
  </code></pre>
  
  <p><strong>I know how to rename it, but how can this be disabled?</strong></p>
