This article gives an example of how the Go language determines whether a file or folder exists. To share for your reference, specific as follows:

Golang determines if a file is a bit weird based on the error message it returns while manipulating the file, not directly based on the path

Version 1:

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

Version 2: Lite version

func IsExist(path string) bool {
    _, err := os.Stat(path)
    return err == nil || os.IsExist(err)
    // or
    //return err == nil || !os.IsNotExist(err)
    // or
    //return !os.IsNotExist(err)

I hope this article has been helpful in Go programming.
