If you do not have Microsoft Office installed on your computer, or if Microsoft Office is installed but
you have associated Microsoft Office file types with LibreOffice, then when you double-click on the
following files, they open in LibreOffice:
• A Word file (*.doc or *.docx) opens in Writer.
• An Excel file (*.xls or *.xlsx) opens in Calc.
• A PowerPoint file (*.ppt or *.pptx) opens in Impress.
If you did not associate the file types and Microsoft Office is installed on your computer, then when
you double-click on a Microsoft Office file, it opens using the appropriate Microsoft Office
component.
For more information on opening files, see “Opening existing documents” on page 27.
Quickstarter
When LibreOffice is installed on computers running Windows or Linux, a Quickstarter feature may
also be installed. When Quickstarter is activated, the necessary library files are loaded when the
computer system is started, resulting in a shorter startup time for LibreOffice components.
Computers with a Mac operating system do not have a Quickstarter.
Activating Quickstarter
On computers operating a Linux or Windows operating system, the default installation of
LibreOffice does not set the Quickstarter to load automatically. To activate it:
1) Open LibreOffice.
