Just in case your next question is going to be how to get the file name or other info. Perl has a good way of parsing (that is independent of operating systems):

Code:
 perl -ane 'BEGIN { use File::Basename; } {($n,$d,$t)=fileparse(@F); print $d,"\n"}' yourfile
 
basically 
$n  is your filename
$d directory
$t is the type

Code:
$ perl -F/ -lane 'pop @F;print join("/",@F),"/";' input.txt
/MEDIA/DISK1/
/MEDIA/DISK1/
/MEDIA/DISK2/PART1/
/IMPORT/
