File created by QuickBooks, an application used for entering and storing financial data; contains a log of transactions that have been entered since the last backup of the .QBA file.

The QBA.TLG file is created during the backup as long as you have set a verification level. There are three verify options: Complete Verification - The recommended option, if you select it, QuickBooks will check your file for any problems. It takes a little longer than other options but is more thorough. Quicker Verification - Selecting this option will have QuickBooks check only the most vital parts of your company file. This option is not as thorough as the Complete Verification. No Verification - By selecting this option QuickBooks will quickly back up a file but is not comprehensive. This option will not create a QBA.TLG file. NOTE: If you accidentally lose data, your most recent backup and the QBA.TLG file can be used by Technical Support to recover your data.
