Here's an interesting one! I thought that there was a 'bunch' of wasted space due to all of the 'screwed up' cluser sizes, but when I used the dir *:/v command, I found out I was right! I do think that the W98 file system uses 512 byte clusters for 'quite a while', so that should fix that complaint. As for stacker, I have used it, I like it (especially in small systems), but if it 'fails', I haven't found any recovery that works! I don't use any compression for that reason! If I need more space, I 'chuck in' another HD! Pick up a 'preview' copy of W98 for the new allocation description. (Maybe 'borrow' a copy!) Thoughts, Ken

Chaz, Folks, tell me: Does Solaris, or HP, or OS2, or mainframe IBM, or anything else you can think of, have these size limitations and huge percentage of wasted disk space caused by the Microsoft FAT system? I don't really know but since you mentioned OS/2 maybe this link will help answer the question.... HPFS files are allocated based on a 512 byte granularity instead of a cluster size, therefore fragmentation is greatly reduced. Also HPFS is especially efficient when handling large partition sizes, > 100 MB, and large numbers of files, >500. One thing you should look out for is to not allocate more than 5000 files in a sub-directory or directory. Allocating more than 5000 files can lead to degraded performance. The HPFS file system shipped with the OS/2 Warp product has a cache limit of 2 MB. software.ibm.com Derek
