Be careful what you say here. I think that the most you can say is that, at maximum compression settings, Compactor usually does a comparable job to Stuffit Deluxe, and that its Compression/Time is (always?) higher than Stuffit Deluxe (on Best level). In other words, Compactor is fast and compresses comparably to Stuffit Deluxe-Best. This means that sometimes Compactor compresses better and sometimes Stuffit compresses better. Compactor is faster (I hesitate to say always, but I think it may be true for sufficiently large files, say > 10K, and, of course, all other parameters equal.) There are times (or files, actually--frequently sounds and pictures) when Stuffit (Classic) will do a better compression job than Compactor. So be careful what you say. +-------------------------------------------------------------------+ | Vincent Del Vecchio \ #include | | Box 4834 \ #include | | 5125 Margaret Morrison St.\ BITNET: vd09+%andrew@cmuccvma.bitnet | | Pittsburgh, PA 15213 \ UUCP: harvard!andrew.cmu.edu!vd09 | | (412) 268-4441 \ Internet: vd09+@andrew.cmu.edu | +-------------------------------------------------------------------+
