How to delete file using C++17 filesystem library

This post is also available in: Deutsch (German)

To remove a file (for example test.txt) use remove from the C++17 filesystem library:


Full example:

#include <experimental/filesystem>
using namespace std::experimental::filesystem;

int main() {

In case you are using GCC, you need to compile the file like this:

g++ -o delete-cpp17 delete-cpp17.cpp -lstdc++fs

You need to link the stdc++fs library so the functions from the C++17 filesystem library are available to your program.

Note that remove does not recursively remove directories! Use remove_all or see How to recursively delete directory using C++17 filesystem library
