There are hundreds of files in the main directory with core.18132 etc. All are around 6mb in size, and they're not in the unzipped ubbthreads directory on SG's hard drive. We would like to know what they are, and why they're there. We think they are the data for the posts, but we aren't sure. We thought the database would have kept those in order. Is it safe to delete them, because they are taking up huge amounts of disk space, or are they necessary?
