when I use sourcetree add subtree, I find that will always add failed, the path is : 
\_Work\2_Git\TestModule\Assets\Test\SubTree. the folder TestModule is a git library ,the folder Test and Test\SubTree has not been created yet. and when I create subtree, it will tips me error: pathspec 'Assets\Test\SubTree' did not match any file(s) known to git.
finally, I find change the path to \_Work\2_Git\TestModule\Assets/Test/SubTree,
will be right. on windows, I am accustomed to use \ to path. can you change it to smart? whatever I use \ to path, it can be normally.
and I also test if folder "Test\SubTree" is exist, as long as I use \ will be failed, use / will be ok.
Hope to be able to fix this problem as soon as possible
