Finding duplicate files

In the realm of data management, a common challenge is identifying and managing duplicate files. In our example, the findDuplicateFiles function became a tool of choice for this task. Its purpose was straightforward: to locate and catalog duplicate files within a given directory. Let’s investigate how this function operates:

func findDuplicateFiles(rootDir string) (map[string][]string, error) {
  duplicates := make(map[string][]string)
  err := filepath.Walk(rootDir, func(path string, info os.FileInfo, err error) error {
    if err != nil {
      return err
    }
    if !info.IsDir() {
      hash, err := computeFileHash(path)
      if err != nil {
        return err
      }
