QuickBooks, accounting software from Intuit, uses QBMB files to store backups of company data. A backup can include the information needed to restore a company file, such as accounts, transactions and company settings.
The QBMB file is intended for recovery or transfer within QuickBooks. It is not the active company file used for routine editing; QuickBooks restores its contents to a working company file.
QBMB is associated particularly with QuickBooks for Mac, while QuickBooks is also available for Microsoft Windows. The file should be restored with a QuickBooks version that supports this backup type.
Open or restore the file from within QuickBooks. In QuickBooks for Mac, use the command for opening or restoring a company and select the QBMB backup file.
QuickBooks may ask where to save the restored company file.
QBMB files are backup files, so they are not normally converted directly to another format. Restore the backup in QuickBooks to create a working company file.
The backup may be transferred to another QuickBooks user for restoration. After restoration, QuickBooks can provide any export options supported by the installed version, but the backup itself should be preserved if it may be needed for recovery.
