Hi, thanks for your contribution. Sorry for the delay, only now I am continuing to work on this project.
I think that GetObjectAttributes, that handle the internal of searching the lower case tree the shouldn't get an upper case path. The higher levels should handle it and pass a lower case name to it. I still need to fix it, but I want to think how I want that the api will look like when I will add option to create files.

The workaround for #13 right now is passing --inject-path in lower case.
