### Problem description Ref #1210 ### Implementation description Call [`SetFileTime()`](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-setfiletime) everytime `FileProvider::save()` is called. ### Additional things I moved the call to `File::close()` from `FileProvider::open()` to `FileProvider::close()` because `SetFileTime()` requires a file handler as input, so I need `File::m_file` to be valid.
