Hi All, I am attempting to write a program to read CSv files from several sub-directories and process them by adding a date field and part of the file name to the new file which is again in CSV format. Directory: c:\ Sub-Dirs : 20010101, 20010102 ................. CSV Files in each directory abc_a.csv, abc_ab.csv abc_se.csv abc_po.csv abc_**** ......... Extract the data from each file merge the date(obtained from the sub- directory) in date9. format and whatever appears after the _(underscore ) in the file name . example File abc_a in directory 20010101: 1,se,oo,poll output 1,se,oo,poll,01JAN2001,a The program should read all the sub-directories in the directory in this case c:\ and process all files and write them to a separate location on say another drive or directory in the same csv format . All assistance is much appreciated as usual. Sa
