### Read Microsoft Compound File Binary Format

Source: https://github.com/richardlehane/mscfb/blob/master/README.md

Opens a file, creates a new mscfb reader, and iterates through directory entries, printing their names and content. Ensure the file path is correct and handle potential errors during file opening and reading.

```go
file, _ := os.Open("test/test.doc")
defer file.Close()
doc, err := mscfb.New(file)
if err != nil {
  log.Fatal(err)
}
for entry, err := doc.Next(); err == nil; entry, err = doc.Next() {
  buf := make([]byte, 512)
  i, _ := doc.Read(buf)
  if i > 0 {
    fmt.Println(buf[:i])
  }
  fmt.Println(entry.Name)
}
```
