Some computers display SVG files within a folder as HTML files. It's weird, we know. They're actually SVG files.
Your computer might think that a browser is the best way to open an SVG file, so it may display SVG files as HTML files.
You can still use the SVG files as usual with your software of choice. Please open them from within the software, because double-clicking directly on them may not launch the correct program.
For example, if you're using Cricut Design Space, go to New Project, Upload, Upload Image, etc., and navigate to the SVG file.
