First of all, THANKS 😄

• manager.php: return new Exclude(['storage' => $storage, 'exclude' => ['.snapshot']]); should use a config.php parameter to have the needed flexibility for defining excluded path component names.
  return new Exclude(['storage' => $storage, 'exclude' => \OC::$server->getSystemConfig()->getValue('excluded_directories', []]);
• exclude.php: private function excludedPath($path) {
  Standard strpos is not working as we do have path delimiters like / and \.
  We need to have an exact match of the search string between delimiters.
  See also the test cases in the original PR.
  And, because of Windows, path components and search string must be converted to lower case.
  Please see also original PR at
  static public function isForbiddenFileOrDir($FileOrDir, $ed = array()) { where you see what and why I did that. You just would need to remove the blacklist parts to have a working function. It also manages a non existent config.php parameter.

Hello @rullzer, do you have any news on that?
When thinking about to use nextcloud, this is a very important functionality...

This was just a proof of concept. Feel free to fork.

This is revived and moved in the Nextcloud repo 🎉 🎂

@mmattel if you could have a look perhaps at how to do what you propose, help would be super welcome... Doing this in a more sustainable way seems the right way to go of course.
