The way Golang determines whether a file or folder exists is to use the error value returned by the os.Stat() function to determine:
If the returned error is nil, Indicates that the file or folder exists
If the returned error type is judged to be true using os.IsNotExist(), it indicates that the file or folder does not exist
If the returned error is of other types, it does not Determine whether it exists
Determine whether the given path file/folder exists:
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 }
