About
What is .DOC?
DOC is the legacy binary file format used by Microsoft Word. It stores text, formatting, images, tables, macros, and document structure within a proprietary OLE compound file. DOC was the dominant format for word-processing documents prior to the adoption of DOCX.
History
Origin of DOC
The file format was introduced by Microsoft in 1983 as the native format for Microsoft Word. It became one of the most widely used word-processing formats throughout the 1990s and early 2000s. DOC is a proprietary binary format using OLE Compound File storage, encapsulating text, formatting, embedded media, macros, and other components. In 2007, Microsoft replaced the binary format with the XML-based format, though DOC remains supported for compatibility with legacy documents.
