Hello, I have read the two previous threads about these files, but I have a question about WHY these files are so huge now... There are currently 91 files in this directory. 420-428.dat are each about 1.7MB in size... 429-449.dat are each about 2.5MB in size... 450-457.dat are each about 12KB in size (??) 458-490.dat start at about 3.8MB in size... 491.dat for some reason jumps to 39MB in size... 492-494.dat jump up to 171, 167 and 175MB in size 495-498.dat drop back down to about 27MB in size 499.dat jumps back up to about 135MB then The last 11, 500-510, are again back up to about 175MB each... Why are these files so huge, and Why were all of the previous ones so much smaller? What could have changed (*I* did NOT upgrade or change ANYTHING when these file size changes jumped beyond the 2-4MB range) to cause these files to all of a sudden grow to such a huge size and fill up my C: partition? Help!!
