[comp.sys.ibm.pc.misc] ZIP files over 640k

koh@eng.umd.edu (Young Je Koh) (01/03/91)

Help !!!

I created a ZIP file which is over 640k.
(I have a system with 4MB main memory)

Now, when I try to unzip, the system gives me something like
"Insufficient Memory" error. (maybe it was "Program too big to fit in memory").

Anyway, does anyone know of a way to sidestep this problem???

Well, do you perchance have any Memory resident programs that you could take
out???  (Not permenantly, just to unzip the file.)  Just an idea,

Now, that's different. I have a "lowly" 640k system, and I regularly
create huge Zipfiles. (Ghostscript is over 700k zipped... I had to tar
it on to 2 floppies)

The question is, did you build a self-extracting Zipfile? If so, you may
not be able to execute it and disolve it. However, you should be able to
extract the members with PKUNZIP. Just give a full filename, so PKUNZIP
doesn't assume the .zip extension

It may be you don't have enough DISK memory? There would have to be room
on your disk for the ZIP file *and* for all the unZIPped files. Same is
true when you ZIP a bunch of files, even with the "delete-when-zipped"
option, you need the space for the ZIPed file to start with.
	Hope your problem is this simple...		-ted-

I have created ZIP files which are 4MB in size on a 640K system
with no trouble; PKZip does not hold the whole thing in memory.
PKZip needs a small amount of scratch work memory and enough
memory to load the program in DOS (or you will get the "Insufficient
memory to load program" message).  If you get that message before
the PKZip signon message, you probably have too many bulky TSRs
loaded which are eating up your conventional DOS memory.  If you
*do* get the signon message and then a memory error, then you have
just enough free conventional memory to run PKZip, but not enough
for the scratch area.  In either case, check your TSR usage.

BTW, I have worked with large ZIPs with PKZip v1.01 through 1.1 with
no difficulty.
