filesystems "remove_all" vulnerability is not defined error

Question

Hello i started c++ and im using Visual Studio 2017 and i want deletin all files/folder inside a folder and i tried this code:

#include <iostream>
#include <filesystem>

using namespace std;

int main()
{
    remove_all("C:\myfolder");
    printf("All items deleted!");

    return 0;
}

remove(); is works for me but remove_all(); doesn't work even i use #include <filesystem>

This is what i what i get while im using remove_all();:

Severity Code Description Project File Line Hide Status Error (active) E0020 "remove_all" vulnerability is not defined.

is it possible to fix? or there another method to delete all files inside a folder?

Not: My VisualStudio is so laggy and sometimes it stay displays error even i fix it. Thanks

My c++ version:

Answer 1

I modified the snippet: added filesystem:: and \\

#include <iostream>
#include <filesystem>

using namespace std;

int main()
{
    filesystem::remove_all("XX:\\XX\\TestFolder");
    printf("All items deleted!");

    return 0;
}

And use the C++ 17 in Project's properties.(Right click the project and you will see the properties page on the last line )
