how to input multiple .txt files
how to input multiple .txt files?
A data folder has lots of .txt files from different customers.
Want to read all these .txt files to different master files:
such as:
cust1.xx.txt, cust1.xxx.txt, cust1.xxxx.txt,.............. to master file: X.txt
cust2.xx.txt, cust2.xxx.txt, cust2.xxxx.txt,.............. to master file: Y.txt
Thanks!
