QuickBooks writes messages about what is happening in QuickBooks to a special log file, which we will call just "the log file:"
The log file contains QuickBooks messages, as well as information created by the Verify Data, Rebuild Data, and Condense Data utilities. It does not show General Protection Fault or Invalid Page Fault messages or messages or errors from other programs. New entries and errors are added to the end (or bottom) of the log file. The file includes date and time stamps with each log entry to help you identify the most recent entries.
