Microsoft Windows NT 4 (and later) uses the Windows NT Registry File (REGF) to store system and application related data, e.g. configurations, most recently used (MRU) files.

MIME types

File signature

REGF has the following file signature:

hexadecimal: 72 65 67 66

ASCII: regf

File types

There are multiple types of REGF files:

  • normal (data) file
  • transaction log file

Transactional Registry (TxR)

In Vista the Transactional Registry (TxR) was introduced. TxR creates transaction log files similar to:

  •  %FILE%{%GUID%}.TM.blf
  •  %FILE%{%GUID%}.TMContainer00000000000000000001.regtrans-ms
  •  %FILE%{%GUID%}.TMContainer00000000000000000002.regtrans-ms

Where %FILE% is the name of the REGF normal (data) file, e.g. NTUSER.DAT and %GUID% a string representation of a GUID/UUID.

TxR is similar to Transactional NTFS (TxF) and uses the Common Log File System (CLFS).

Contents

The REGF basically consists of a set of hive bins. These hive bins contain cells that make up a hierarchy of keys and values.
