Yes my friend but it works for me too in w7

And I have a NAS with my movies on linux, so I ask to a friend of mine to write a script to change the folders modification date, and He gave me this...

#!/bin/bash
#
# fix movie folder date
# by vpeter for pjgm
#
# ref
# http://unix.stackexchange.com/questions/...ecursively
#

# find folders in curent folder
find -mindepth 1 -maxdepth 1 -type d | while read dir ; do
echo -n "Modifying date '$dir' "
# go down
cd "$dir"
# get reference file date
#refFile=$(find -mindepth 1 -maxdepth 1 \( -name "*.avi" -o -name "*.mkv" \) -printf '%T+=%p\n' | sort -n | tail -n 1 | sed 's/[^=]*=//')
# first find .avi file
refFile=$(find -mindepth 1 -maxdepth 1 -name '*.avi' -printf '%T+=%p\n' | sort -n | tail -n 1 | sed 's/[^=]*=//')
if [ ! -n "$refFile" ]; then
# then find .mkv file
refFile=$(find -mindepth 1 -maxdepth 1 -name '*.mkv' -printf '%T+=%p\n' | sort -n | tail -n 1 | sed 's/[^=]*=//')
fi
# file set
if [ ! -n "$refFile" ]; then
echo " - no reference .avi|.mkv file found"
else
echo "using file '$refFile'"
# set date first on folder
touch -r "$refFile" .
# set date on all the other files too
touch -r "$refFile" *
fi
# go up
cd ..
done

works for me...
Now the modification date of my folders have the same date as the mkv or Avi files that they have inside them.
