It is meant to work. There have been some bugs in this area in the past, I believe they have been fixed. It also doesn't perform well with large trees of files from a speed perspective. Something like git allows for much faster operations as git is designed to do tracking of this kind of thing. So yes, it should work but isn't optimal with really large trees. Cheers, Richard
