I have a multiple polygons inside of a big polygon. Is it possible to select all the small polygons if they do not have any attribute in the attribute table?

Mapping Center Answer:

If you have simgle part polygons, you can use the "Shape_Area" field and select all the polygons that are below certain value in square units. If your data do not have an area field, you can add one and easily calculate the values using the Calculate Geometry function.

If you have multipart polygons, then you can use the Data Reviewer to find the interior parts of the polygon.
