route CHA01\, will generate a new file name
CHA01001.XLS.
After exist the Datalogger, then execute again,  the data
will save to the CHA01001.XLS until Data column reach
to 30,000 columns, then  will generate a new file, for
example CHA01002.XLS

3)Under the folder CHA01\, if the total files more

than 99 files, will generate anew route, such as
CHA02\ ........

4)The file's route structure :

CHA01\ 

CHA01001.XLS
CHA01002.XLS
.....................
CHA01099.XLS

CHA02\

CHA02001.XLS
CHA02002.XLS
