Files
main.go is the actual code, while main.exe is the compiled code. Feel free to install that file and rename it to whatever you want. After installing, you can send it to someone. They'll usually run it within their downloads, which would be a pretty hard hit depending on their file/directory population.
The code works by using a recursive function (using redefinition) to range through all directories within the current directory, clearing the files within each, including the current directory.
Forfeiting
The code will forfeit if it's unable to read the current directory, or even get it, adding a fun twist.
Result
