The ccp command conditionally copies files to a target directory if they are missing from the target directory or have a different size, time, or date on the target directory. It preserves the name, read/write mode (read-only attribute), system and hidden attributes, and modification date and time of the files that it copies. It can copy entire subdirectory trees as XCOPY /S does or just portions of subdirectory trees. It can also exclude files and subdirectory trees that match one or more optional exclusion patterns.
