Should I uninstall all previous versions in any case? But how can I keep my project files, TMs etc. of previous versions? When I uninstall it, also the folder "Studio …" with all its content is uninstalled and gets lost, doesn't it?

You recommend to remove previous versions before installing the latest version, right? But I remember that some years ago Trados wouldn’t find the files any more after I had moved them to a different folder. Since then I only save my projects at the standard (default) “Studio…”-folder and don’t move them any longer.

For example, I also still have my old 2014 version on my computer even though I don’t use it any longer. But if I unstall it, all the project folders and TMs … in the folder “Studio 2014” get lost, don’t they? Or can I move them just to any other folder? How will “Studio 2021” then be able to open/use them?
