title: remove backslash in a file with Powershell
body: <p>I cannot remove a string containing a backslash with Powershell</p>
  
  <pre><code>(Get-Content $file.fullName).replace('\\mystring', ') | Set-Content $file.fullName
  </code></pre>
  
  <p>It works if I had to remove 'mystring' only</p>
  
  <pre><code>(Get-Content $file.fullName).replace('mystring', ') | Set-Content $file.fullName
  </code></pre>
  
  <p>But with a backslash no. What's wrong?</p>
