As suggest by Go developers, use `filepath.WalkDir` instead of `filepath.Walk` because [*Walk is less efficient than WalkDir, introduced in Go 1.16, which avoids calling `os.Lstat` on every file or directory visited](https://pkg.go.dev/path/filepath#Walk). This proposition address that, in a similar way as https://github.com/go-gitea/gitea/pull/22392 did. Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
