QuickBooks Error 6190: What It Means and How to Fix It (2026)
Quick Answer
Error 6190 indicates that the company file is open on another computer with changes that have not been saved. QuickBooks cannot open the file until the other session completes.
What Error 6190 Actually Means
Error 6190 indicates that the company file is open on another computer with changes that have not been saved. QuickBooks cannot open the file until the other session completes. Company file errors are the most serious category because they can indicate actual data damage. Always back up your file before attempting any fix.
Common causes:
- Company file data structure is damaged or corrupted
- File was improperly closed (crash, power failure, forced shutdown)
- Multiple users writing to the file simultaneously without proper locking
- Disk errors on the storage device
- File has grown too large for available system memory
How to Fix Error 6190
Create a backup immediately
Before attempting any fix, make a copy of your .QBW file. Copy it to a USB drive or different location. If the file cannot be opened, copy the .QBW file directly through File Explorer.
Run Verify Data
Open the company file and go to File > Utilities > Verify Data. This checks the internal data structure for errors and reports what it finds without making changes.
Run Rebuild Data
If Verify reports errors, run File > Utilities > Rebuild Data. QuickBooks will create a backup automatically, then attempt to repair the data structure. This can take a long time for large files.
Try opening a backup
If the main file cannot be repaired, try restoring from your most recent backup (.QBB file). You will lose any transactions entered after the backup date.
Contact Intuit Data Recovery
For severely damaged files, Intuit offers a professional data recovery service. This is a paid service but can recover data from files that Verify/Rebuild cannot fix.
Why Error 6190 Keeps Coming Back
Company file errors recur when the root cause (disk problems, power instability, improper shutdown procedures) is not addressed. Replace failing hard drives, use a UPS on the server, and ensure all users close QuickBooks properly before shutting down.

Frequently Asked Questions
What does Error 6190 mean?
Error 6190 indicates that the company file is open on another computer with changes that have not been saved. QuickBooks cannot open the file until the other session completes.
Can I recover all my data?
In most cases, Verify and Rebuild can fix the file with no data loss. If those fail, restoring from a backup loses only the transactions since the backup date. Professional data recovery can often extract everything.
How often should I back up my company file?
Daily if you enter transactions daily. At minimum, weekly. QuickBooks can schedule automatic backups. Store backups on a separate drive from the company file.
Is my file too big?
QuickBooks Desktop can handle files up to 1.5 GB but performance degrades above 500 MB. If your file is large, consider using the Condense Data utility to archive old transactions.
How does Hubricon protect my financial data?
Hubricon stores your financial data in an encrypted, managed database with automatic daily backups and point-in-time recovery. Unlike local files, there is no risk of data corruption from power failures, disk errors, or improper shutdowns.
