A QuickBooks Portable company file (.qbm) is a compact version of your company data file that contains ONLY your financial data, and because it is much smaller than a backup (.qbw) it can be sent by email or saved to portable media.
A QuickBooks portable company file contains only the financial data for your company. Unlike a backup file, it doesn’t contain related files such as letters, logos, images, and templates. It also doesn’t contain a transaction log (.tlg file), which can be used to restore transaction data with the help of Intuit Technical Support if damage or loss occurs.
You can use a portable company file whenever you need to move your company financial data to another computer or location or send it to another person.
Another benefit of the Portable company file is that it has been known to help resolve problems with large QuickBooks files that have a high number of DB (database) file fragments.
