Hi Nadav,
Thanks for your help. I have followed your instructions but i cannot get it to work. I used the LIST DIRECTORY to list the files in the directory - that works. However, how do I read each of the 200 files using READ FROM SPREADSHEET FILE without me having to manually select each of the 200 files? So, if I use LIST DIRECTORY to list all 200 files in an array, how do I get each of these to open and store the data in a 2D array? Here is what I have done (File called read_files.VI) Could you please help me? Thank you very much in advance.
