Importing an SDLXLIFF into a TM? Where do I find that option?
Just right-click on the TM in the Translation Memories view and select import:
Then click on Add Files and choose sdlxliff from the list of compatible types:
I can't seem to find a possibility to do batch tasks after I finalized the files/project
This is because finalising the project finishes it. If you want to leave your project available then just save the target files instead of finalising it. Once you finalise you need to go the files view and select the files you want to update (probably all of them) and then right-click and select Revert to SDLXLIFF file:
Now when you go to the batch tasks they should all be available.
and the second option. Would you be so kind as to point that out?
I think you are referring to the use of fields to export part of a TM. Basically, if you used fields to identify the TUs you just updated then when you right click to export from your Main TM you can use a filter here to export only some of the TUs based on a number of criteria. In this case I left the date, so could export only recently added TUs:
But there are various options here. Is this what you meant?
