Getting: java.nio.file.filesystemexception: C:\users\anar.memmedov\desktop\file.xlsx -> C:\users\anar.memmedov\desktop\ko\file.xlsx: the process cannot access the file because it is being used by anot

This is my code, which accept generally .xlsx format file and insert to database and also move accept file to my specified folder. When I trying to move it, I have getting this error:

Normally, it successfully writes the received excel file to the database, but when I added the new feature, which move in specified folder, I started getting this error. I started using threads or something, but it didn't help.

public static void acceptExcellFileAndInsertToDatabase(File file) {

    try {
        String phoneNumber = "";
        String textMessage = "";
        FileInputStream excelFile = new FileInputStream(file);

        Path sourcePath = Paths.get(String.valueOf(file));
        Path targetPath = Paths.get("C:\\Users\\anar.memmedov\\Desktop\\ko\\" + sourcePath.getFileName());

        Files.move(sourcePath, targetPath);

        Workbook workbook = new XSSFWorkbook(excelFile);
        Sheet datatypeSheet = workbook.getSheetAt(0);
        Iterator<row> iterator = datatypeSheet.iterator();
        while (iterator.hasNext()) {

            Row currentRow = iterator.next();
            Iterator<cell> cellIterator = currentRow.iterator();

            while (cellIterator.hasNext()) {
                Cell currentCell = cellIterator.next();
                if (currentCell.getCellTypeEnum() == CellType.NUMERIC) {
                    phoneNumber = NumberToTextConverter.toText(currentCell.getNumericCellValue());
                } else if (currentCell.getCellTypeEnum() == CellType.STRING) {
                    textMessage = String.valueOf(currentCell.getStringCellValue());
                }

            }

        }
        insertExcellFileToDb(phoneNumber, textMessage);
        System.out.println(phoneNumber + " " + textMessage);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
