I have used Path Finder almost for Cut & Paste in file browsing, but I found defaults command for adding cut & paste to MacOSX Finder.

$ defaults write com.apple.finder AllowCutForItems -bool yes
$ defaults write com.apple.finder AllowPasteForItems -bool yes
$ killall Finder

I like several convenient functions of Path Finder which are hidden or Finder.app doesn't have. Path Finder is sometimes unstable and I have to refresh its file browser after files are created of edited. This malfunction were irritating me so often.

This commands are so useful for me to discard Path Finder and switch back to default Finder.app.

I misunderstood this. It only moves a file into .Trash. And Paste doesn't work.

Then, later, I found another little utility "pathsnagger" for alternate fuction of Path Finder.
It enables copying file path in context menu.
