That's not 'fragementation' in the same sense as the term is used in the MSDOS world. Read about it any of the books on the BSD system. You'll see that fragments are areas where piece of file are store that won't fit in a full allocation block (typically 4K or 8K). It's just the amount of file-pieces stored. When the file is next added to these pieces are reclaimed and put in contiguous blocks if the addition is enough to fill out a full allocation. -- bv@wjv.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
