notice that $file is not enclosed in the sub shell (in between
``) as an argument to echo. if the $file happens to have end
blanks, they will be eaten up. try...
f=' p q r '; echo $( echo $f | sed 's/ /_/g' )
...output /should/ have been '_p_q_r_', but is 'p_q_r'.

notice that you have enclosed the string to echo in double quotes,
which preserves the spaces.
