Hi  jack zhong  - on your question around splitting SDLXLIFF files - see for example the SDLXLIFF toolkit app at RWS AppStore. Also while it is desirable to have a more robust handling of large files (Studio 2022 SR2 has some improvements in that area BTW), I also consider this a "get it right at the source" problem. If a file with 300,000 words and 50,000 segments enters the translation supply chain, something has gone wrong "at the source", i.e. where you get the file from. It is not good practice to work with such unwieldy files in any use case, including translation. But we acknowledge this happens very often so the CAT tool has to handle this as robustly as possible.

Just to add what to what Daniel mentioned, I'd actually recommend you use studioViews. This is far more robust, has more capability, and you can easily export/import split files within your project which make it much easier to work.  So this one:
