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
