However, this local storage leaves QuickBooks data accessible to data loss due to hardware failures or software issues. Therefore, it is crucial to maintain frequent backups of QBW files. In this article, read how to troubleshoot QuickBooks corrupt data files and prevent it in the future.

• Once the tool completes the repair, select “OK.”
• Now, return to the “File” menu, hover over “Utilities,” and choose “Verify Data.”
• The tool will then scan your file for any data issues. If QuickBooks doesn’t detect any problems you’ll see an “OK” message showing that your company file is free of data damage.
• However, if QuickBooks does find an issue with your company file during the verification process then you’ll have the option to select “Rebuild Now.”
• If you still encounter data problems even after rebuilding your company file you may want to try the process again. But if the initial rebuild took more than 2 hours.
