Hi,
We are using AIX 5.2. I am trying to unzip a file with *.zip extension. When I give unzip command, it terminate with following error:

skipping: PreProcessed072006.txt need PK compat. v4.5 (can do v2.0)

Unzip version I am using:
UnZip 5.52 of 28 February 2005, by Info-ZIP.

The file I am trying to unzip is greater than 4GB.
Plz if anybody can help me.

Thanks
Aqeel Anwar

what is your limits user.
try this command

Quote:

ulimit -a

time(seconds) unlimited
file(blocks) 2097151 # maximun file size
data(kbytes) 131072
stack(kbytes) 32768
memory(kbytes) 32768
coredump(blocks) 0
nofiles(descriptors) 2000

You can modified this attributs ( fsize fsize_hard ) with the chuser command

and also, look if your destination filesystem accepts files larger than 4gigabyts.

the app needs to be built with LARGE_FILES support...
try building unzip from opensource.
