I get a huge ABC.csv file that I would like to sort out into a number of new csvs - a,b,c. Depending on each ABC.csv string's pattern I want to put it into one of the newly created csv files - a,b, or c. Could you please help me with this leaving out the string analysis part. I'd like the program to check if there are a,b, and c already in the designated MyFolder folder and if there are not create them anew. Also, every time I run the program, the new data have to override the old ones.
Thanks you very much
