Data file not found

So I'm trying to upload my unity game to www.gamefront.com so my friends can see what I'm working on. (I'm not done with the game yet) For some reason it won't upload two files at once. Since the data file has to be with the .exe file, how could I do this? Would I have to upload both files and they'll have to download both? I'm a little confused here. I Googled it and couldn't find my answer, thanks for all responses in advance!

*Edit* Ok I found out how. If you don't know, you have to make a new folder and put the data file and .exe file in there, and zip that folder, it worked for me!
