Actually, since you dont' hae to read the whole file to find out where the 10th file's data starts, you actually consume less bandwidth. Disk size still seems to be growing exponentially so I don't think that is quite as large of a concern. The bigger problem with that is that Bloatware (tm) packages keep growing faster than the disks do. :) -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
