No it doesn't delete your files. Hombre from the post told it to delete his files and was then shocked when it did. It even warns you that it's about to delete your files. Then on top of that, post person wasn't even using source control, so they can't get their files back. Don't mess with the source control options if you're not using source control. Don't just randomly click buttons without reading, if your project files are super critical. Don't only have a single version of your entire project in a single place on one computer. This person obviously has no idea what they're doing, which is fine, but they don't belong anywhere near a 5000 file project.
