The notion of a program that cannot be copied but only moved makes little sense.A file move operation reads the file from the source location and creates a copy at the destination location. It then marks the original file for deletion by the operating system on the source computer. The computer that is doing the copying cannot force the source computer to delete the file, only mark it as such.The computer that is holding the source file has no control over the computer that is writing the copy of the file to the destination location, It cannot force the destination computer to erase its copy if the deletion of the original file fails.The notion that only one copy of a program can exist is possible if all of the involved computers have software that can control the copy, such that it will not finalize the copy until the source location is securely erased, this is often classed as Digital Rights Management software.In the context of the film transferring a file across many computers, where each one would not be under the scope of such DRM software means any one of those servers could have taken a copy and the notion a file can only exist in one place and a second copy cannot be created is not possible.
