Use this tool to copy files from one location to another, including local drives or networked drives. Perfect to run as part of a backup utility as it does not delete any files. Be Careful though, it WILL overwrite any files with the same names without a prompt.
It will build a mirror file/directory structure as it runs. Powershell must be available as some earlier Windows versions do not have it installed. As this is a PS1 file it can be run from schedulers to form part of a backup strategy, overwriting earlier copies of any files it has copied on an earlier run.
