This guy really has no idea how shell extensions work on Windows. Other apps that overlay icons over files work the same way, including Tortoise Git/Hg/Svn. Every time Windows Explorer displays a directory, it must check if it should draw an icon over files in that directory. It doesn't know if the directory is "special" (aka, Dropbox, git repo, etc) so it makes the check every time for all files in all directories. https://msdn.microsoft.com/en-us/library/windows/desktop/bb761267(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/bb7...
