My wife and I both run separate projects in UFT on Computer No1. I have made a back up of my project and library files and restored to my older slower machine, computer No2. I now enter additional information, sources, individuals etc into my project on computer No2. My wife continues to use computer No1 adding information to her project. I make a backup of my updated project on computer No2 and restore it to computer No1. My project will be updated but will updating the library files remove any changes my wife has made on Computer No1.Sorry this sounds complicated but I don't want to screw up my wife's project and suffer the resulting consequences.Any help will be much appreciated.
