WD My Book 4TB

I am looking at getting the above as my main back up device. I currently use my passport ultra and I use it just to back up my dslr files. If I bought the my book would it be the case of just plug in and set to copy photo files like my passport or would it ask to download software again and potentialy confuse itself? I am not very computer literate so appreciate your time


I saw you other post with a similar question and replied to it.
