What is a OTG file
Files with the extension .otg are used by OASIS OpenDocument programs. They contain information used for the creation of vector graphics. The name “template file” indicates that the file can be used as a basis or template to create vector graphics with similar information. In order to do so, the OTG file contains information about the layout and other drawing information. On the basis of this file, users can create actual drawings that are then saved as ODG files.
OTG files use XML formatting to store template information. Since the file is a template file, it cannot be used as a ready-to-view image format. To share, show, or view the actual vector image, the file has to be exported as an ODG in one of the programs using the OTG extension, such as OpenOffice Draw or LibreOffice Draw. These programs are open-source alternatives to the Microsoft Office suite.
Here's a small, but not exhaustive list of programs that can open OTG documents:
- LibreOffice (Windows, Mac & Linux)
- OpenOffice Draw (Windows, Mac & Linux)
- Planamesa NeoOffice (Mac)
