The QuickBooks File Doctor is a tool from Intuit that is designed to diagnose and fix common problems with QuickBooks data files and your Windows and network configuration, including:
- Data corruption
- Windows setup problems
- Network setup problems
The tool has its limits. It only works with:
- .qbw and .qba files
- QuickBooks company files (.qbw) smaller than 2 Gb
Further, diagnosing network setup problems may not work if you have multiple QuickBooks versions installed on your computer. In some cases the tool may diagnose a problem but then be unable to fix it. That typically depends on whether a QuickBooks Auto Data Recovery folder exists. Auto Data Recovery (ADR) is another Intuit data protection tool available to some QuickBooks users.
