Assuming by "files" you mean rows, and assuming a table named t1, a column
in it named id, and you having done something like ...

    SELECT @idmax := MAX( id ) FROM t1;

then this gives you missing numbers:

    SELECT t1.id
    FROM t1 LEFT JOIN t1 AS t2
    ON t1.id = t2.id-1
    WHERE t2.id IS NULL AND t1.id < @idmax;

Once MySQL gives us subqueries in 4.1 (December?), it'll be easier ...

    SELECT id AS id1 from t1
    WHERE id < idmax AND
    NOT EXISTS (SELECT id FROM t1 WHERE id = id1 - 1);
