What is a .DOC file?
DOC is the legacy binary Microsoft Word format used before Office 2007, stored in an OLE2 compound file rather than zipped XML.
- Did you know
- The .doc binary format dates to Word for Windows in 1989 and was Word’s default until DOCX arrived in 2007.
- Word debuted in 1983 as “Multi-Tool Word” for Xenix, and the .doc extension has carried that lineage ever since.
- A .doc uses Microsoft's OLE Compound File container, effectively a little filesystem inside one file, which is why old Word documents can hide deleted text and metadata.
- What Analyser shows you
- Open and read Microsoft Office documents - modern Word, Excel and PowerPoint (DOCX, XLSX, PPTX), their template, macro-enabled and slideshow variants (DOTX, XLTX, POTX, DOCM, XLSM, PPTM, PPSX), the binary Excel workbook (XLSB), and the legacy 97-2003 binaries (DOC, XLS, PPT) - plus the OpenDocument family in every shape: zipped and flat single-XML text, spreadsheets, presentations and graphics (ODT, ODS, ODP, ODG, FODT, FODS), templates (OTT, OTS, OTP, OTG), legacy StarOffice (SXW, SXC, SXD), and EPUB e-books, shown as page previews with selectable text, tables, sheets and slides. Excel workbooks (XLSX and its macro/template variants, plus the binary XLSB) and OpenDocument spreadsheets (ODS) additionally open in a full analysis workbench alongside the sheet preview - a virtualised grid with sort, filter, search and column tools, a group-by summary, and a chart builder - to explore the data itself, not just preview it.
