Files with .ONE extension are created by Microsoft OneNote application. OneNote lets you gather information using the application as if you are using your draftpad for taking notes. OneNote files can contain different elements that can be placed at non-fixed locations on document pages. These elements may contain text, digitized handwriting, and objects copied from other applications including images, drawings and multimedia (audio/video) clips.
A file with .svgz extension is a compressed version of Scalable Vector Graphics (.SVG) file. It is compressed with gzip compression and contains data in XML format. SVGZ files support transparency, gradients, animations, and filters. SVGZ files are smaller in size as compared to the default SVG files and this reduced file size helps transfer the graphics files.
You can also convert ONE into many other file formats. Please see the complete list below.
