Learn to find QBWin.log or QuickBooks.log files to help you determine the cause of certain errors in your QuickBooks Desktop company file.
QuickBooks Desktop logs program messages and errors, including information created by Verify, Rebuild, and Condense Data utilities, in a specific file. In Windows, the file is called QBWin.log while for Mac, it is called QuickBooks.log.
Note: Errors like "IsQBInUseLockFilePresentAndLocked...LCK can't be found. Error = 2" in QBWin.log is not a sign of data damage and should not be considered as one when troubleshooting data damage.
