File signature

OE5 DBX files start with hexadecimal: 0xcf 0xad 0x12 0xfe. For now it is assumed that this is the file signature. It is followed by a content class identifier (CLSID), which is unique for the type of DBX file.

File types

Although DBX probably contains a minor/major version (offset: 20 and 24) until now it is unknown how it affects the file type.

Contents

The contents of a DBX file is dependent on the content CLSID.

  • Message Database (CLSID: 6F74FDC5-E366-11d1-9A4E-00C04FA309D4)
  • Folder Database (CLSID: 6F74FDC6-E366-11d1-9A4E-00C04FA309D4)
