It might sound weird.

I have the main Data files in a folder `cas_06.cas` etc etc.

(I have all the files. The Data ones are the biggest (GBs) And would save the most time)

I have tried placing them where they are to be downloaded to. But it doesn't seem to want to use/update these files.

Is there anyway to `verify cache` as you could in Steam, for it to check current contents and what else is needed?

Or any other way for it to accept these files on my PC without re-downloading them. Thanks
