I back up my library & data file every 2 weeks. When I recently went to backup the files they had expanded about 3 1/2 times. The library from 827047 to 3001873 and data from 13462356 to 44338187. I had had just a few updates. What could of caused this & what should I do about it? I have TMG but have not converted yet. I have plenty of disk storage & running on Windows ME. Need help. Thank you.
