How to use a single CE001.format for mutlitple .csv files ?

Dear Friends

How to use a single CE001.format for mutlitple .csv files ?

First time i created graphs using File > Import Wizard and the File > import ASCII.
During that time i created 1 file format say CE001.format.
During that time i used copper.csv file
for draw graph. The Candle chart is successfully drawn.

Now my intension is to use the same file format CE001.format for using gold.csv file for draw graph.
Note : Both csv file are same column type so there is no seperate .format file required.

What i made is I directly used File > import ASCII by using Files of type : CE001.format
and file name : gold.csv
(without using File > Import Wizard), But this is not working why ?

To draw candle chart for each and every file, If i have to use both the File > Import Wizard and the File > import ASCII
(i.e., for each file a individual format file is to be created or not)
Or any other alternate methods ?

Anybody please explain

thanks
