So, all if / else must have a following end ? I realize it must be
somewhere, but do they always necessarily follow the if / else or
perhaps could they be further down depending on the code logic ?

I think guilty as charged.  Using a combo of tabs and spaces in Scite.
Here (and I dont' want to keep posting new designs) but here is
something that looks logical to me:  What is happening with this code
is it keeps asking about the same file.  I thought the 'each do' would
continue to loop through.  Doesn't seem to be the case.  I tried
adding something to the while like 'until pic_names.length' , didn't
go over well. :)
btw , i removed tabs and spaces from paste, and then spaced in Gmail.

pic_names = Dir['C:/PicturesMoved/*.{BMP,bmp}']

      pic_names.each do |name| #start of array loop
      continue = true # setting up the conditon to end the while loop
                 while (continue)
                 fcheck = FileTest.exist?(name) #should be confirming
files exist in directory

#probably this is out of context though I don't

#believe it's doing any damage
                       if fcheck == false
                        puts 'file does not exist'

                       else
                        puts 'Do you wish to move ' + name +
'file?,"yes" or "no" ?'
                           decision = gets.chomp.downcase

                       end # for 1st if block perhaps wrong ?

                       if decision == 'no'
                          puts 'file will not be moved'
                          pic_names.delete(name)

                          end # for 2nd if block
                      end # for array loop
                  end # for while loop
