CopyFile File copies a single file from src to dst

func CopyWithCtx

func CopyWithCtx(ctx context.Context, out io.Writer, in io.Reader, size int64, progress func(percentage int)) error

CopyWithCtx slightly modified function signature: - context has been added in order to propagate cancelation - I do not return the number of bytes written, has it is not useful in my use case

func CreateNestedDirectory

func CreateNestedDirectory(path string) error

CreateNestedDirectory create nested directory

func CreateNestedFile

func CreateNestedFile(path string) (*os.File, error)
