title: remove existing file returns FileNotFoundError
body: <p>I have an existing file in a mounted folder, which I verify by</p>
  <pre><code>os.path.isfile(config.inpath + file)
  True
  </code></pre>
  <p>But the following returns a FileNotFoundError</p>
  <pre><code>os.remove(config.inpath + file)
  *** FileNotFoundError: [Errno 2] No such file or directory:
  </code></pre>
  <p>Also,</p>
  <pre><code>os.system('rm ' + config.inpath + file)
  </code></pre>
  <p>doesn't work. However, I can remove the file from the terminal.</p>
  <p>Any idea why this is not working within python?</p>
  <p><strong>EDIT:</strong></p>
  <p>I don't know if this helps, but here would be the exact error message</p>
  <pre><code>FileNotFoundError: [Errno 2] No such file or directory: '/home/operations/mnt/CustomerFolder/TESTSSTEM/filename.xml'
  </code></pre>
  <p>Unfortunately,</p>
  <pre><code>os.remove(os.path.join(config.inpfad, file))
  
  FileNotFoundError: [Errno 2] No such file or directory:
  </code></pre>
  <p>also doesn't work.</p>
  <p>The file ist not a symbolic link either.</p>
