[AccessD] OT RE: Rar vs winzip

Mike,

LOL, I know all of that.  I was just posting an "interesting (and maybe
valuable) to know" kind of email.  I wasn't expecting anything like the
response I received.

Let me tell you something.  I zipped a hundred gig file.  It took RAR about
28 HOURS to zip it.  It takes Winzip about FOUR times as long to do the
same.  I scheduled it to RAR over the weekend, not over lunch!  ;-)

I was just pointing out that is useful to know your options.  I would NEVER
schedule a RAR during a time that I had to use the computer.  OTOH I would
schedule a Winzip when I had to use the computer.  I would NEVER try to
Winzip a 100g file.  It would just take so many days that it would be silly
to even contemplate.  I have 400 gigs of data I want to zip up (or RAR up).
Using Winzip is a non starter.  It would be next Christmas before it got
done.  BUT... I also have to be careful to not do the RAR while I need the
computer.

Again, it is just useful to know what choices I have and how they effect how
I work.

In this day and age, I would expect such utilities to allow me to designate
a % of total CPU power to apply to the task.  Neither one does TTBOMK,
though I haven't gone looking either.

John, RAR is not as popular as is WinZip.  You would forcing others to
purchase RAR to uncompress your files.  That could be annoying.  Also, one
of the many reasons for the multi-core processors is so that you can do
multiple things at one time stretched across the processors which is suppose
to make you more productive; this is different from single core processors.
But if an application consumes all processors then I would have to think
that is a flaw unless there is specifically an option to use one or more
processors.

If you are concerned about the zipping time then schedule it for
lunch/dinner or ...

Mike...
