This project is based on https://github.com/LordMike/NtfsLib. I have made the NTFSCopy tool usable with execute-assembly in Cobalt Strike. This was done using ILMerge to make a single executable without any dependencies, and removing the fancy colored progress bar which Cobalt Strike couldn't handle (seems like Console.Seek() was throwing an exception).
Clone the repository and build the NTFSCopy project within the solution.
