    const downloadPathBuffer = Buffer.from(fs.readFileSync(`../downloads/${year}`));
    const dataPathBuffer = Buffer.from(fs.readFileSync(`../data/${year}`));

    var checkBuffer = downloadPathBuffer.includes(dataPathBuffer);
    
    if(checkBuffer)
    {
        readDataFile(downloadPath, callbackResult => {
