.QB2007 File Extension
What is a QB2007 file?
Company accounting file created by the Mac version of QuickBooks, a small business accounting program; contains financial data, such as income and expenses for a company; also stores report definitions, letters, and a company profile; used for tracking income and expenses, as well as for filing taxes.
Mac versions of QuickBooks use the software release year as part of the file extension. For example, the QuickBooks 2010 extension is .QB2010.
NOTE: Since QB2007 files were used for a previous tax year, they are now legacy.
