csv files are text files, usually written in ASCII or ISO-8896-1 (which is compatible with ASCII).

fopen() it, fgetl() to read a line. fclose() after you are done.

Hi Walter, i also want to creat a file list of the large csv data i have. when i write dir *.csv i get all data displayed but when i try to write a script say

dir=('C:\Lisajustin\Vib')

Listdir=sprintf('%d%d',dir, '\*.csv');

i get error message ??? Error using ==> sprintf Function is not defined for 'struct' inputs.

what could be the problem
