@L3n I think that in order to help you further I need to know more about what your dependencies are, how many different commands you have, etc.
Also, I'm going on vacation for a week so I'll not be replying for a while

I'd expect `unique_ptr` to use `delete`, while it should use `delete[]`. Why aren't you using one of the standard containers instead of trying to encapsulate a raw array? That as introduction, make sure you submit your code for review on codereview.stackexchange.com! — Ulrich Eckhardt 14 secs ago

If your code works but you just want comments for potential improvement, you should post it to Code Review. That said, the only suggestions I would make are to use `@echo off` once you're happy with how the code runs, and to put the first `"` on each of the `set` commands on the left side of the variable name (like `set "sourcedir=C:\Users\Murray\Documents\MainFolder"`, etc.) so that the variable value itself doesn't include quotes. — SomethingDark 14 secs ago
