There are a few different ways to open a document file, depending on what type it is.
The most common document files are Microsoft Word documents (often identified by the file extension ‘.doc’ or ‘.docx’). To open these files, you will need a word processing program such as Microsoft Word, OpenOffice, or a web-based program like Google Docs. Once you have a program installed, simply double-click the file or open it from within the program.
Other types of document files include Adobe Acrobat documents (with the file extension ‘.pdf’), which require the free Adobe Acrobat Reader program to be installed before they can be viewed. Once the program is installed, double-clicking the file will open it in the program.
Finally, Rich Text Format (RTF) files (with the file extension ‘.rtf’) can be opened in most word processing software, although formatting may occur.
No matter what type of document file you are opening, make sure your computer is running up-to-date antivirus and anti-malware software to avoid potential security risks.
