If you have had a 341 meeting of creditors, then you are not "filing" bankruptcy -- you have already "filed."
You can ask the court to dismiss the bankruptcy for "cause," however, for Chapter 7, you must convince the court that the dismissal will not prejudice your creditors interests. Other grounds for dismissal would be failure to file papers as required by 11 USC 521 (e.g., tax returns).
After a dismissal, if you file Chapter 7 again within 12 months, the automatic stay will be lifted after 30 days, and your creditors can continue to attempt to collect against you.
Hope this helps.
