Thank You, pagefault, for the answer.
I know how upload file to crowdin, but I'd like to know more about download. I have finished my translation there in the crowdin after I uploaded earlier translation file. (I have added about 300-400 strings)
Now I'd like to check how it looks in the paint.net. (Some strings sometimes are too long for example. )
Hope there is possibility to download finished translation from crowdin.
