I have had this problem in the past. Try opening a blank DB next to your open DB. Point and drag everything...tables, queries, forms, reports, macros, modules... You may have to re-establish your relationships (can't remember if you can drag and drop them) but you will see the size of your database drop dramatically. Every time you try something new Access adds it to the SQL section of the DB. If you delete and item it does not delete the SQL statement therefore it keeps building up. Without data most Access DB are not really that big! It's all the trial and error that begins to ADD UP! Try this... the worse thing that can happen is you waste a little time.
