Hi. I am manually upgrading to 1.3.9. I wanted to find out if uploading the new data this way is ok:

I am going into each folder in zc, clicking upload, selecting all the files out of my 1.3.9h zipped folder, and uploading them which does overwrite some of the old ones.

The only thing I have noticed so far is some old files not being included in the 1.3.9h files.....wasn't sure if these should stay or I should delete them out.
