Include additional files for the DLL with JNA

I'm having a problem running a DLL in Java via JNA, the DLL looks for a file that is in the same folder named "propriedades.properties" , this DLL works normally, but when using JNA it does not find the file. It seems that JNA runs the DLL somewhere else, not in its source folder ("That's just a guess on my part"). The code I use is as follows:

System.setProperty("jna.library.path", "C:\");
        System.setProperty("jna.debug_load", "true");
        System.setProperty("jna.debug_load.jna", "true");

DllMicros micros = (DllMicros) Native.loadLibrary("dllmicros", DllMicros.class);

micros.CallSat(_Id, _ConfigVenda, _DadosVendas, _Error);

I activated the debug to try to identify the problem, but it does not give any clue, since the DLL is included normally, anyway I will include it as well.

Ocorreu um erro: O arquivo de propriedades n�o p�de ser carregado! // Este erro é lançado pela DLL que não encontra o arquivo na pasta em que está sendo executada

If anyone has any tips, I'm grateful.
