"Note I said easiest not quickest"

Yeah, I noticed.....

Not all files that were transferred are messed-up. Could it still be possible that some files would have gotten corrupted if they were interpreted as text and others were sent ok without being modified to text? Or, would all the transferred files have been corrupted equally?

I'm new to FTP, so could someone tell me how to force a binary transfer and I'll give that a try? Is that just something in the settings?
