The default log location for Advance is C:\inetpub\wwwroot\Logs. The Logs folder always appears in the root deployment directory for Advance. If you edited the log location settings in the Advance installer configuration settings file, the logs will be in your custom location.
All log files are written to the same folder. Individual Advance applications write to their own log files, prefixed with the name of the application. For example, the Advance root application writes to log files with the naming format of HdaRoot_{date}.log.
