See filepath.Walk (https://golang.org/pkg/path/filepath/#Walk)
If you wish to recurse with ioutil.ReadDir or File.Readdir (https://golang.org/pkg/os/#File.Readdir), you have to do it manually. Nested structs -- it depends what you are doing. I would simplify it to: type Stat struct { FileCount int64 DirCount int64 Bytes int64 } When I want to keep per directory, then I would use: type Info struct { Path string Total Stat Current Stat Dirs []Info } type Stat struct { FileCount int64 DirCount int64 Bytes int64 } Btw. have you done the Go tour?
