How likely is it that today 2018 or later we will not be able to read or unpack backups made with WinZip 11.1?
Can our customers simply continue using this version of WinZip 11.1?
What are the pros and cons?
if we suggest move to a better or latest software. Will we be able to read previous backups made with WinZip 11.1?
These remote customers have proved many times they can be really special.
so before proposing and making any change, I'll rather check on most possibilities
and most important, we need to prevent a situation where backups are not useful.
