In the menu file>utilities> there is an option for Condense, you can try that, but Condense works about 60-70% of the time accurately.  Print your present critical financial reports (inventory valuation, sales tax liability, a/r and a/p, P&L, balance sheet and any others you worry about), make a back up from the file menu and move it to another folder for safekeeping.  Then do the condense, print the same reports - they MUST match or delete the condensed file and restore  the original back up file

If you want the first two utilities on this page will accurately create a new file for you, then you can back up the original and copy it to a CD for archival purposes.
