The files downloaded from your ftp site have the Archive attribute set, so I suppose that I'll make them all that way. Between your and David Rasmussen's replies, I'm now initiated into the "md5sum fraternity". First question which pops up in my head: Will the file properties such as name, attributes, and dates created/modified/accessed affect the md5sum values? I ask mostly because files where the ftp download was interrupted (then resumed later) have my download date for "date modified", rather than your original upload date. I guess I'll find out. <:o) As for getting all 7.5 GB on my two-year-old 12 GB hard drive, maybe temporarily, then burn CD copies and remove those less important. Yep, my next system will have a 60 MB hard drive (at least)!? WP
