Journal files capture the actions taken by the software during a session of Revit LT, from the time the software starts to the time it stops. These text files can be used to troubleshoot technical problems with the software.
Revit LT creates a new journal file each time you use the software. The journal file with the highest number is the most recent file. By default, journal files reside in the following location:
The Journal folder is hidden by default in Windows.
If you encounter problems during a Revit session, your support provider may ask you to send the journal file and any backup files to help with the troubleshooting process. If you do not encounter problems during a session, the journal file is of little use and can be deleted. To automate the deletion of old journal files, see General Options.
