QNX4 fs using QNX7.1   
Hi, I'm workink on a system that uses both 6.5 and 7.1  versions.
For legacy purpose we have a QNX4 formatted partition on a sd card shared among 
6.5 and 7.1.
The problem is that in the 7.x version the QNX4 fs is no more supported: why?
I've not found any way to access a QNX4 partition from 7.1 ...
 is it possible to have back the support for qnx4 also in 7.x? 
Thanks
M. Sangalli

Re: QNX4 fs using QNX7.1   
QNX4 fs support was removed in QNX7.0 back in 2017. I don't see it getting added back.
http://www.qnx.com/developers/docs/7.0.0/#com.qnx.doc.qnxsdp.migration/topic/filesystems.html

QNX6 fs is supported by 6.5, 6.6, 7.0. 7.1
http://www.qnx.com/developers/docs/6.5.0SP1.update/index.html#com.qnx.doc.neutrino_utilities/f/fs-qnx6.so.html

Alternatively FAT32, EXT2, and NTFS are also possible.

Re: QNX4 fs using QNX7.1   
Thanks, John: I know that qnx4 has been discontinoed, but my problem is to
have access to qnx4 partition using a qnx7.1 system, for legacy purposes.
Copy a qnx4 data over a qnx6 fs using a 6.5 system should be a problem,
I can do it, but is should be complicated to do in some installations
Compatibility does not seem a priority  issue for qnx  :-)
