I am just wondering why files had been pilling in this directory and of a sudden all of the 3 CAS servers stopped getting this files a month ago. The last files are all one month ago. So what does this directory do, could I empty this directories, they have around 3,000 files in them. All files are like below. Exchange 2010 sp2 rollup 6
