Text 1 Digital Preservation Department / The National Archives 02 Aug 2005 04/2024 (v.118): An additional internal signature, name updated for the original internal signature, description update, library of congress identifier, documentation links and vendor. Submitted by Institute of the History of Charles University and Archive of Charles University, Preservica, Brigham Young University and The Church of Jesus Christ of Latter-Day Saints. 02 Aug 2005 application/zip MIME com.pkware.zip-archive Apple Uniform Type Identifier x-fmt/263 PUID zip File extension 200 ZIP Format Signature 1 Local file header at BOF (with maximum offset of 4 bytes) + central file header and end of central directory near EOF. NB. The signature byte sequence is currently massaged to steer around the known PRONOM bug in the area of right fragment matching when the longest fragment is not nearest EOF. The first fragment in the EOF byte sequence has been shortened by 1 byte to ensure that the subsequent fragment is the longest. This abbreviation does not reduce the overall signature strength too much and so will hopefully not result in any false pisitive identification. When the PRONOM bug has been fixed, the "504B01" at the start of the EOF byte sequence should be extended to "504B0102", and this note reduced. 1 Absolute from BOF 0 4 504B0304 1 Absolute from EOF 0 Little-endian 504B01{43-65531}504B0506{18-65531} 2311 ZIP Format Signature 2 BOF; Offset: 0; Magic Bytes: 'PK' followed by 0x05060000 denoting the end of the central directory 1 Absolute from BOF 0 0 504B05060000 Has lower priority than 745 OpenOffice Writer Has lower priority than 746 OpenOffice Calc Has lower priority than 747 OpenOffice Impress Has lower priority than 748 OpenOffice Draw Has lower priority than 777 Java Archive Format Has lower priority than 778 OpenDocument Format Has lower priority than 783 OpenDocument Database Format Has lower priority than 876 SIARD (Software-Independent Archiving of Relational Databases) Has lower priority than 910 Microsoft Office Open XML Has lower priority than 1033 OpenDocument Text Has lower priority than 1034 OpenDocument Text Has lower priority than 1035 OpenDocument Presentation Has lower priority than 1036 OpenDocument Presentation Has lower priority than 1037 OpenDocument Spreadsheet Has lower priority than 1038 OpenDocument Spreadsheet Has lower priority than 1039 OpenDocument Graphics Has lower priority than 1040 OpenDocument Graphics Has lower priority than 1206 OpenDocument Database Format Has lower priority than 1215 CorelDraw Drawing Has lower priority than 1216 CorelDraw Drawing Has lower priority than 1231 OpenDocument Database Format Has lower priority than 1269 Apple iBook format Has lower priority than 1270 ePub Format Has lower priority than 2393 ISDOCX Information System Document Has lower priority than 2396 ISDOCX Information System Document Has lower priority than 2518 EndNote Library Has lower priority than 2519 EndNote Compressed Library Has lower priority than 2521 EndNote Compressed Library Has lower priority than 3916 Android Package File
