- Make a new project using the memory from the previous project. However, I did not manually "create" a memory when creating the original project. So how on earth do I create a memory from that project after the fact?
In Trados, go File > New > New Translation Memory. After you've created the (empty) translation memory, in the side bar on the left, click Translation Memories so that you can see a list of translation memories. Right-click the translation memory and select "Import". Then select the SDLXLIFF file(s) that you had just finished translating. This will import your translation into that translation memory.
The next step would be to ensure that that translation memory is "active" in your new project, but you'll figure it out.
