Takaaki-san,
Your suggestion needs a path to the file. I don't think there's a quick way to enter the path to the file. I may be missing.
If you don't want to use the OpenEncodeFile.tmBundle you can enter such paths with the attached tmCommand.
Simply write ~/De
and press OPTION+APPLE+TAB.
See a Screenmovie of it here:

Please note: I changed the key binding to OPTION+APPLE+TAB!
dewa mata,
Hans
