Hi @zhiquan114514 . Could you provide example code? Can you clarify if the issue you are seeing is due to an IntelliSense error (squiggle), or something else? I'm able to use the filesystem header and namespace without any IntelliSense errors, with a simple example and default settings on Windows:

#include <iostream>
#include <filesystem>

namespace fs = std::filesystem;

int main() {
    // Define the path for the new directory
    fs::path dirPath = "example_dir";

    // Check if the directory already exists
    if (!fs::exists(dirPath)) {
        // Create the directory
        fs::create_directory(dirPath);
        std::cout << "Directory created: " << dirPath << std::endl;
    } else {
        std::cout << "Directory already exists: " << dirPath << std::endl;
    }

    return 0;
}

Assuming you're referring to an IntelliSense issue, could you provide the output of the C/C++: Log Diagnostics command while that file is open?

@Colengms I don't think it is a intelliSense error, I hit the debug button then everything appears. And I compile the example code you gave. However I do notice there there is a warning indicating that i am not using c++17 but actually I am using it.

Hi @zhiquan114514 . That warning would appear to be coming from another extension. Problems logged by the C/C++ Extension would be indicated as C/C++, not cpp.
