1) I found it on several pages that were on the server, in the folder you pointed out, but not on my local drive even though I had copied all the files down before looking. I guess new files are created dynamically when some changes are made? otherwise I don't know why they didn't copy down which is why I couldn't find the files.
2) Ok. Maybe I can make it not visible. thanks.
3) There was nothing obvious that would tell me how to do it. I ended up shift+selecting, updating, and, yes, it worked that way.
