Filesystem
An implementation of C++17 std::filesystem
.... It should work with Android NDK, Emscripten and I even had reports of it being used on iOS (within sandboxing constraints) and with v1.5.6 there is experimental support for QNX. The support of Android NDK, Emscripten, QNX, and since 1.5.14 GNU/Hurd and Haiku is not backed up by automated testing but PRs and bug reports are welcome for those too and they are reported to work.
