[yogihardi]

What version of Go are you using (go version)?

$ go version
go version go1.17.6 darwin/amd64

What did you do?

unpack textfile with the following code:

	tmpFile, err := ioutil.TempFile(os.TempDir(), "")
	if err != nil {
		log.Fatal("Cannot create temporary file", err)
	}

	// Remember to clean up the file afterwards
	defer os.Remove(tmpFile.Name())

	// Example writing to the file
	text := []byte("lorem ipsum")
	if _, err = tmpFile.Write(text); err != nil {
		log.Fatal("Failed to write to temporary file", err)
	}
	tmpFile.Close()

	fileToProcess := tmpFile.Name()
	fOpen, err := os.Open(fileToProcess)
	if err != nil {
		log.Fatal(err)
	}
	defer fOpen.Close()

	_, err = unpackit.Unpack(fOpen, "/tmp/unpackit")
	if err != nil {
		log.Fatal(err)
	}

What did you expect to see?

proper error message, ie: unsupported file
