changes after review
changes l10n after review
check list of users with access to the file from the bottom to the top. This way we avoid calling getFileInfo() on every dir, which creates a lot of overhead, especially for external storages
if one public link share was found, we don't have to check it for the other folders
for external storages we never reach the path 'files', instead we need to leave the loop if no further parent exists
