z files from an old QNX system which needs to be unpacked in preferable Centos.
These files are packed with the QNX pack method and there is no Virtual Machine (VMWARE) available to load QNX and unpack these files.
I've tried all the available extraction programs, but no one is able to unpack these. File filename gives data as result I've tried the following:
- gunzip
- uncompress
- tar
- winrar
- 7z
- unzip
Output in Centos:
-rwxr--r-- 1 root root 896 Mar 11 05:15 PMITN01.z
[root@green update]# zcat PMITN01.z
zcat: PMITN01.z: not in gzip format
[root@green update]# gunzip PMITN01.z
gunzip: PMITN01.z: not in gzip format
[root@green update]# uncompress -v PMITN01.z
PMITN01.z - no .Z suffix
[root@green update]# tar -zxvf PMITN01.z
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors
[root@green update]# cat PMITN01.z | cpio -imdv
cpio: premature end of archive
[root@green update]# file PMITN01.z
PMITN01.z: data
After installing freeze/melt:
[root@green update]# cp PMITN01.z PMITN01.z.F
[root@green update]# melt PMITN01
PMITN01.F: No such file or directory
[root@green update]# melt PMITN01.z
PMITN01.z.F: not in frozen format
The only valuable search I've found is the following OpenQNX forum.
-----UPDATE--------
I've added the file here so you can see/check what kind of file it is.
I still haven't found an answer for my question, so I don't know why answers get upvoted....
To make it more complicated the system used probably split the files into multiple files, here is a ll -hal output:

As you can see it's not a clear split on filesize.
