[PRODIG] Action/batch converting to jpg

[PThompson8]

I'm working with PS 7 Windows XP

I have quite a number of large (70mb) tif files that need to be converted to jpgs.

I want to retain the tif files and make jepgs of various sizes.
My ideal would be to have a number of folders called:
jpg  quality 5, quality 8, max quality. (or alternatively jpg 2mb, jpg 5mb, jpg 10mb) then to simply drag the tif over the folder and have them copied as an appropriately sized jpg.

After studying "PS help" I understand that I can't have an action which converts to another format (file format I presume)

Am I wanting the impossible or have I misunderstood the "help"?

Thanks for any suggestions or work arounds.
