I've run into some trouble with zoo and was hoping someone could help me
out.
I've used zoo to backup my 32MB C drive which resulted in a 11.9MB zoo file.
Unfortunately now I cannot retrieve all of the files from the archive. When
trying to extract an old copy of my autoexec.bat I get the following:
F:\> zoo e disk_c autoexec.bat
Zoo: FATAL: Ran out of memory.
This file and the others I have tried to extract are near the end of the
archive. I have been able to extract a file from the first half of the
archive.
When running zoo I have 545KB of memory available. I am using zoo 2.1 on an
NCR PC-916 (80386).
Does anyone know how to get around this problem? If not does anyone know
what the breaking point is for zoo, how many files can I put in before it
chokes on extraction?

At extraction time zoo 2.01 allocates memory for each filename being extracted (without freeing it, unfortunately). It will probably run out of memory only after a lot of pathnames (several hundred to a couple of thousand, depending on name length). It doesn't use long pointers and so is limited to 64K data. (This will be fixed in the next release.) Possible work-arounds: 1. Make a fresh copy of the archive, eliminate most files from the copy it by selecting with wildcards, then extract needed files. E.g. copy disk_c.zoo G:x.zoo zoo D G:x *.com *.exe *.c *.h *.i zoo PE G;x zoo e G:x autoexec.bat You will need enough disk space to copy the archive and pack it. 2. Extract the archive on another system on which the 64K segment limit doesn't apply. (VAX/VMS, BSD, System V, Amiga, Atari). 3. Use looz to extract. It doesn't do anything special with filenames and allocates no memory for them. -- Rahul Dhesi <dhesi@bsu-cs.bsu.edu> UUCP: ...!{iuvax,pur-ee}!bsu-cs!dhesi

I used stuff | zoo to back up a subdirectory onto part of a HD floppy. The zoo file is about 300K. This having been done several months ago, I tried to update the zoo file from the same subdirectory, and got the same FATAL message. I was able to make a new zoo archive from the same subdirectory, but that took a lot more time than an update. I was also able to update a zoo archive that backed up a much smaller subdirectory. I'm hoping that zoox (the multivolume zoo) doesn't have this problem, but I haven't tried it yet. M. B.

I tried to use zoox this weekend with the multivolume feature, and got a message to the effect: FATAL: out of memory or target disk full. What good is a multivolume archiver that can only back up to one volume :-) Anyway, I went back to using PC DOS 3.3's BACKUP. Stefan

Does anyone use DeskView 1.0 with or without QEMM 4.2?? I was wondering: 1) How much memory would you say is adaquate? 2) Is it true that you can run 2 programs simulataneous? A friend of mine said I could run a BBS in the background and play a game in the forground. Is this true? Is anyone using DeskView to do this exact thing? How about running a BBS in the background throught COM1: and using procomm through COM2:? 3) Is there a way to use memory from 640K to 1 Meg for resident programs? Or is this just used for BIOS and MOS 4.01?? By the way, I meant DeskView 386.
