For MSDict, the type is often 'Dict' or 'Mspd' , creator 'MSDc' . 2.2 Custom Dictionary Header Immediately after the PDB header (or sometimes as the first record), MSDict stores a private header. Its exact length varies, but typical fields (reverse‑engineered): msdict pdb files

def extract_definitions(pdb_path): with open(pdb_path, 'rb') as f: name, num_records = read_pdb_header(f) records = read_record_entries(f, num_records) | Offset (from start of custom header) |

def read_record_entries(f, num_records): entries = [] for _ in range(num_records): data = f.read(8) offset = struct.unpack('>I', data[0:4])[0] attr = data[4] unique_id = data[5:8] entries.append((offset, attr, unique_id)) return entries 2 = UTF‑16
