Hi George, > Its always been my belief that large folders cause multi level > directory block chaining in traditional UNIX fs.
I expect the majority of nmh users are using ext3 or ext4 filesystems, as shown by ‘df -T’, though perhaps we have many Apple users who have something else. I don't think ext* still use Thompson's original approach of levels of data blocks to hold the extra (filename, inode) pairs. What I've found a problem with ext* filesystems is when a directory has millions of files. Deleting them took a week because I had to remove them in small batches with seconds of pause between to allow the machine to recover. But Norm's some way under that. :-) -- Cheers, Ralph.
