Apple Script for copying path and name and pasting it in Spotlight Comment box Mac OS X 10.9.5 (and 10.11.4)
Building upon jackjr300's answer, you can add the path to the comment with this modified script:

set input to choose file with prompt "Select files (to put the file name into the Spotlight Comment)" with multiple selections allowed
tell application "Finder"
    repeat with i in input
        tell item i to try
            set tName to (get name)
            set tPath to POSIX path of i -- get the path of the file
            set comment to tName &amp; " - " &amp; tPath -- this set the comment to the name of the file, and delete the existing comment
            set name to "Done_" &amp; tName
        end try
    end repeat
end tell


The changes to the original script are these two lines:

set tPath to POSIX path of i -- get the path of the file
set comment to tName &amp; " - " &amp; tPath -- this set the comment to the name of the file, and delete the existing comment


The first line sets tPath to a string containing the path to i. In this case i is the file being examined.

The second line appends the path to the file's comment using the segment: &amp; " - " &amp; tPath. The section between the two double-quotes can be changed to something other than a hyphen.
