Winner a book from booklikes

I have a question for all of you who use booklikes.


I entered into a giveaway and won but it wants me to download the ebook from something called filefactory. 


Being as I have never won anything off of here and I am kind of wondering if this is legit. Is there anyone who can tell me if it is please. 


I don't want to do anything illegal or be involved with something illegal.


Thank you 



The giveaway owner got back with me and sent the file. I feel better knowing that it could have been sent that way.
