If you are referring to Access databases, you can do a search within Explorer for all files with a .mdb, .mde, .adp, .ade, .mda or .mdw extension ( I think thats all of them). When explorer shows you everthing it finds with those file extensions, highlight/select them all, right click and select properties. The properties window will show you the combined size of the files you highlight.
If you aren't doing anything fancy, then just worry about .mdb files (the actual database) and .mda/.mdw (security) files.
