I never knew this until I put on my Unix hat and tried it!

I discovered by chance that you could put in an environment variable into the Window's Explorer address bar and it resolves to the location - path that I typically use daily include %TNS_ADMIN%, %TEMP%, %USERPROFILE%. I only considered doing this when I became frustrated with trying to remember locations - how easy is it on Unix - cd $ORACLE_HOME.  Now, it is just as easy on Windows.



P.S. Some of my work mates said they use this all the time - doh!
