I have to scan a directory with subfolders for each day of the year, containing up to around 400 files. So this will generate more than 10000 files each month. I tried a script using the code sequence "For each ... in ... ". That works very fine, but with very low speed (several hours). Is there a more rapid way e.g. using a macro and system functions to speed up the process. The goal is, to generate a list of files with the complete path, so that I can sort out the ones, for loading the complete data from the files.
