- My comments:
-
- Well, the new ZIP takes it hands down.
-
- I still prefer many of ARJ's commands, such as the ability to split ARJ
- files so their size will fit on floppies. ZIP's version of this feature
- appears to only work if you archive directly to a disk. (From what I
- gathered from the documentation.) Personally, I prefer the flexibility.
-
- As for Zoo... I realize it is portable across a gazillion different
- architechtures, but come on. With zip source available on Unix machines,
- I can see it quickly replacing zoo as the over-all standard (if it hasn't
- already).
-
- Congratulations PKWARE, PKZip's speed and now compression is #1!
