1. If Dev is using source control (I know Git & Azure DevOps) then you can simply get with one of your Devs and ask them to create a Repo for you and show you how to clone it to your local PC and manage it.  There is a learning curve but I really doubt you will regret it.
   • There are are a few ways to manage your teams code merges in Git and it is completely external to TestComplete and works at the file system level.  Any changes you make to files that are under version control will be tracked and managed even outside of TestComplete such as with notepad or even a file system name change or delete. 
   • Git has built in merge conflict resolution.  It will show you the file versions side by side and allow you to choose which file to keep or even select individual changes to resolve the conflict.  Depending on how you setup your repo access you can control this and resolve the conflicts yourself or kick them back to the team member or even go hands off and let team members merge directly.
   • You will need to setup TestComplete to use Git however so TestComplete will show you all the neat Git bells and whistles.

   • Tortoise Git is a nice add on supported in TestComeple that will let your team commit, push, merge, revert and compare code versions.
   • Visual Studio has a very nice interface for working with Git outside of TestComplete that will allow you and your team to manage code versions, history and merges and everything else Git does. 
2. Here there isn't anything other than what I think you may already be doing.
