Forgive me guys, i thought people wouldnt see it if it was in an old post, but schaaksmurf answered my question over there, his answer was:
-V1P3R-, the only tagging program I know with an Excel-like setup is called "The Godfather". It is particularly useful when you need to tag lots, and i mean LOTS of files.
You say you need to tag about 7000 files, well I don't know if it can handle that many files in 1 go, but about 2000 i believe it can handle. Anyway their homepage has a forum so if you should have problems using the program you can always ask for help.
Here's the link: http://users.otenet.gr/~jtcliper/tgf/
Hope the program suits your needs.
again sorry about reposting here.
