title: SVN Diff: Why are some files marked as binary

  <p>Why would my SVN client mark some files as binary?</p>
  
  <p>Specifically, <code>.sql</code> has prop <code>svn:mime-type = application/octet-stream</code> when using TortoiseSVN.</p>
  
  <p>I checked Right-click > Tortoise context menu > Settings > General > Subversion configuration file, and nothing is <em>uncommented</em> in <code>[miscellany]</code> or <code>[auto-props]</code>, so where is the decision coming from?</p>
  
  <p>From what I can see in the related posts, I can "fix it" by either deleting the property on affected files, or globally change the behavior on new files via config/setting, but is there a "simple" way to do both for all affected files?</p>
