A file with an .ai extension is an Adobe Illustrator Artwork file that contains vector graphics on a single page. It uses points to create paths for displaying the image data, thus making it safe from losing image quality if it is enlarged. AI format finds its major usage for logos and print media. AI files can be opened with Adobe Illustrator, Adobe Acrobat DC, PaintShop Pro, and CorelDraw Graphics tools.
Files with .POT extension represent Microsoft PowerPoint template files created by PowerPoint 97-2003 versions. Files created with these versions of Microsoft PowerPoint are in binary format as compared to those created in Office OpenXML file formats using the higher versions of PowerPoint. The files, hence, generated can be used to create presentations that have the same layout and other settings required to be applied to new files. These settings can include styles, backgrounds, color palettes, fonts, and defaults.
