DisplayWrite

Latest revision as of 13:21, 27 February 2025

DisplayWrite was an early Word Processing program built by IBM based on the IBM DisplayWriter dedicated system^[1][2].

[edit] File Information

Depending on version, DisplayWrite saves documents to a proprietary binary format with the extension .DOC^[3][4]. Versions 4, 4.2, and 5 files have the BOF hex values 80000009 20004F7B 4A5D1800 1460 for the first 14 bytes^[5][6][7].

DisplayWrite software cannot save to other word processing formats, making it difficult to migrate content. Many other software titles can import DisplayWrite files, like WordPerfect^[8][9].
