Help with Ghost 15

Hi,

I have ghost 15 and decided to actually use it but i'm finding it a bit confusing. Now i'm pretty tech savvy but i just want a simple program to copy my documents, my music ect to my external hard drive and then if anything changes on the computer, the file on the external hd gets replaced with the updated one (which it does every friday or something). Also i would prefer if the files i backup are left as normal files so i can access them instead of fbf files that i have to use ghost to retrieve. 

 

Can ghost do this or did i buy the wrong program. 

Thanks,

Nikhil.
