#‘path_txt’ is the where you have all your text files (say 100 text files).
#‘path_csv’ is where you’ve saved a CSV that lists the text files names that need to be combined (say text files with names as: “ABC”, “DEF”, #“GHI”, from the 100 total files).

#‘path_save’ is where the final combined file will be saved
