Bit Save Arrays

[bbn.com!mesard@BBN.COM (Wayne Mesard)]

I have a MacIvory model II.  On the Macintosh file system there's a
folder called "System Folder:Ivory:Bit Save Arrays".  It contains 32
files named "BitSave m.n", where m and n are integers.  Some of the
files are empty, but some are as large as 115k.  The modification dates
on the files range from 10/24/89 to 12/14/89.

What are these guys?  They account for 1.7M on my hard disk.  Can I
delete them?  Pretty please?

Thanks for any information.
