// CopyFile copies the source file to the target.
// The most efficient means of copying is used for the platform.
func CopyFile(target, source string) error {
src, err := os.Open(source)
if err != nil {
return errors.Wrapf(err, "failed to open source %s", source)
}
defer src.Close()
tgt, err := os.Create(target)
if err != nil {
return errors.Wrapf(err, "failed to open target %s", target)
}
defer tgt.Close()
return copyFileContent(tgt, src)
}

The current implementation of CopyFile does not support copying metadata.
CopyFile should optionally copy the metadata as in CopyDir
