Can I use airport time capsule 2tb the same way as an external hard drive

I would like to know if I can use it as I would an external hard drive by dragging certain files or folders over to my Mac computer and not just as a backing up device. Where as I would only be able to completely add all files and folders without a choice of particular ones. Can anyone please help me. I would like to purchase it but don't know if I should just go with a simpler external hard drive. I do like the features of the airport but I have noticed a few reviews of people claiming they were not able to select one folder to add or remove. Thanks for the help!
