FAQs!

If Error 6143 is due to file corruption, how often should I create a manual backup of my QuickBooks company file (.QBW)?

It is recommended to create a manual backup of your QuickBooks company file (.QBW) at least once per week. Additionally, you should always create a new backup immediately before and after performing any major actions, such as installing a new QuickBooks update, performing a major data import, or running the Rebuild Data utility (which is sometimes necessary after fixing a corruption error like 6143).

If the company file is damaged (like in Error 6143), can I still rely on my previous QuickBooks Auto Data Recovery (ADR) files?

Yes, the Auto Data Recovery (ADR) feature is a vital safety net. ADR automatically creates backup copies of your company file and the Transaction Log file (.TLG).
If your primary file is corrupted, you can often use the ADR files (found with the .adr extension) to restore your data to a recent state, minimizing data loss before or during the fix for Error 6143. However, you should always try to restore from a standard manual backup (.QBB) first, if one is available.

Can having multiple versions of QuickBooks (e.g., 2024 and 2023) installed cause company file access errors like 6143?

While QuickBooks is designed to allow multiple versions to co-exist on the same computer, having different versions installed can sometimes complicate file path permissions and lead to conflicts, especially if multiple versions try to access the same related program files or services.
➜Always ensure you are opening your specific company file (.QBW) with the correct, corresponding version of QuickBooks it was last updated in. Opening an older company file with a newer QuickBooks version prompts an update, which should be done with caution and a backup.

Could using a very long file path or special characters in the company file’s folder path trigger or contribute to Error 6143?

Yes, having an overly long path, special characters, or spaces in the company file name or folder path can interfere with QuickBooks’ ability to locate and open the file. Some community‑based guidance (and troubleshooting blogs) report this as a factor for 6143‑type issues.
➜Recommendation: Keep file names and folder paths simple; store the company file in a clean, shallow folder structure (e.g., C:\QBFiles\) rather than deeply nested or network‑shared folders.

If I fix Error 6143 by renaming or moving files, will I lose or corrupt my financial data?

Generally, no as long as you are not deleting the primary data file (.QBW) and you have a valid backup. Renaming auxiliary files (.ND, .TLG) or moving the company file location does not delete transaction or accounting data. This is a standard recommendation in 6143‑resolution guides.
Best practice: Always backup your company file before making structural changes (moving, renaming) so you have a fallback if restoration fails.

When should I run the Rebuild Data utility versus the Verify Data utility in QuickBooks?

These are two key tools for company file maintenance:

➜Verify Data: You should run this first. It scans the company file for structural data issues or corruption (like that which causes Error 6143). If it finds an issue, it will recommend that you run the Rebuild Data utility.
➜Rebuild Data: You should only run this after Verify Data has identified problems. Rebuild Data attempts to repair the issues found in the file structure. Always create a backup (.QBB) immediately before running the Rebuild Data utility.
