(txt, codepage is 1252, no labels, delimiter is ',', msq, filters(


The question is, why is this not speeding up my reload times. I'm loading phone call log files, which grow daily. Shouldn't this script ONLY load the new files? Every reaload time grows and grows as my number of log files.

Yes, I meant remove the



I know it won't give you the correct result, but just as a test.
