Make a folder for each file. Then put the appropriate file in the appropriate folder. For example, make a folder titled, "Seeds for Sowing - Vol. I - B". Then put the file named "vol_i_year_b.zip" in that folder. Then go to the file once it is in the folder and click on its name. Make sure that you direct the unzip program to unzip the files to the folder you created for those homilies. All of the homilies will then appear in that folder.
