In CMD, use copy "source path" "destination path" to copy files, and move "source path" "destination path" to move files. Replace the paths with your file's current and desired new locations. In PowerShell, use Copy-Item -Path "source path" -Destination "destination path" to copy, and Move-Item -Path "source path" -Destination "destination path" to move files. These commands allow for file management within the terminal environment.
