A .doc file, which is Microsoft Word's proprietary document format, can be opened and read, edited, shared, printed and saved as a ".doc" file or another file format, such as ".txt" or ".pdf." A ".doc" file can also be imported into files created by other Microsoft Office programs.
Microsoft Word's ".doc" format is used to create word-processing document files that may contain graphics and objects, such as charts and text. A Microsoft Office user can open a ".doc" file in Word to read it and make changes to it. Many formatting options exist, including a large selection of fonts and special text effects. The user can position text, objects and graphics wherever he wishes. Graphics and objects may be created in Word itself, or they can be created in other programs and imported into the document. Slides created in PowerPoint and charts created in Excel are two examples of items that can be imported into a ".doc" file.
A finished document can be emailed as an attachment, printed or imported into files created by other Microsoft Office software, such as PowerPoint. Several users can collaborate on the same ".doc" file and communicate with each other by posting comments to a document. Using the Track Changes feature allows users to see and approve their colleagues' changes. Although ".doc" files are typically used within Microsoft Office programs, several software publishers have programs that are compatible with ".doc" and other Office file formats.
