Roosters,
I'm not sure exactly what you mean by combine. But if all the tables have the same basic type of data fields, ie they're a bunch of customer lists from different branch offices, and you have the same fields & data types (or close to the same), then a Union query will do the trick. Often just a little preliminary tweaking is needed here, such as lopping off un-common fields, or making sure the order of the fields is the same (or aliasing and listing them in the select clause of the union instead of using select *). Then use the union as the base for an append query to the destination.
