# Logs

With failed request tracing enabled, the log files are created and populated in the directory set up in [Configure failed request tracing](https://docs.devolutions.net/server/kb/troubleshooting-articles/failed-request-tracing-with-iis/configure-failed-request-tracing/). By default, the path is **%SystemDrive%\inetpub\logs\FailedReqLogFiles**. There, a folder typically named **W3SVC1** is created when the first case happens.

### W3SVC1 folder content

* XML files (**fr######.xml**): Open an XML file to view the log triggered by the tracing rule.
* XSL file (**freb.xsl**): For the display style, in an XML viewer like Internet Explorer.
