Correct the vague error messages output from twsinst

While upgrading FTAs from IWS 10.1.5 to IWS 10.2.3 we received the following vague and totally unhelpful output from the backup step.

Wed 05 Nov 2025 01:38:39 PM MST backupInstance begin

*****************************************

We have the experience from running twsinst to upgrade literally hundreds of FTAs this year that when the backup step fails, it is most probably because the either the default or specified working directory is not large enough according to twsinst calculations. Our question is why can't the error message say that? 

The 2 error codes by themselves tell the user nothing and are absolutely worthless. Firstly, why can't twsinst actually kick out a registered application AWSFAB error code that we can look up online? AWSFAB062I is not documented online at https://help.hcl-software.com/workloadautomation/v95/common/src_ms/awsmsawsfab.html which is sad because we can't find any AWSFAB updates for 10.1 or 10.2 online. Secondly, we know from other twsinst checks & calculations that you do have more effective messaging that actually defines the problem and points to a solution.

Our suggestion is to go a step further. Use the calculation that is currently determining that directory is not large enough and echo it out as the output message:  "pick a working directory with xMB free" ?
