1. If the error returned is nil, it means that the file or folder exists

2. If the error type returned is true using os.IsNotExist(), it means the file or folder does not exist.

3. If the error type returned is of other types, it is not sure whether it exists. There are

func PathExists(path string) (bool, error) {
    _, err := os.Stat(path)
    if err == nil {
        return true, nil
    }
    if os.IsNotExist(err) {
        return false, nil
    }
    return false, err
}
