the problem appeared after i tried path finder app, i didn't like it, i removed it using cleanmymac, than i used
defaults write -g NSFileViewer -string com.apple.Finder
and
rm Library/preferences/com.apple.finder.plist
now every time i click on show in finder, instead of opening the folder containing the file( the default behaviour of finder), it open the file, for EXP: if the file is a dmg it mount it, if it's a text file it open it on an editor, would any one have any idea how to reset finder
