If I am upgrading versions specified in the subject, and I have downloaded the changed files. All I need to do is unzip the 2.0.6 to 2.0.7 zip file in the main zip file and then upload all the files in that file to the server in place of the older files?
Create a folder on your desktop (name not important)
unzip ALL the files to this folder.
In the folder, you'll see a number of directories, and a number of zip packages....
you must unzip the 2.0.6 -2.0.7 to (preferably) another new folder.
Follow all the other main rules..... and once uploaded, use a web browser and in the address bar. type in....

that should be it. aside from then deleting the 2 directories contrib and install.
(you know, i wish people would stop using zip files, its just so much hassle for most people)
