Are these files needed still, or can i delete the old ones?

it stands for Aktiebolag, which is a swedish word meaning

If your table contains a timestamp field, it will update each time the row
is altered. Otherwise I don't think it's possible.

If I understand you correctly, you are looking for certain items from

You would write that generally as:

FROM table1
LEFT
You might do something like:
SELECT t1.* FROM t1 LEFT JOIN t2 ON(t1.field1=t2.field1 AND field2={fieldvalue}) WHERE
{all kinds of limits} AND t2.field1 IS NULL LIMIT 0,20;
the LEFT JOIN/WHERE idfield IS NULL will join the table and then lists
rows in table 1 that don't exist in table 2
