Task templates are very similar to tasks, but they don't contain computer list or log file list. Templates are stored separately as files in "C:\ProgramData\Event Log Explorer\TaskTemplates\" folder. Task templates are intended to create new tasks quickly based on the template.
To create a template, start creating a task. When the task is ready, click Save button arrow and select Save as template.
Task templates are listed in the Tree under Task templates node. When you double click on a template, Event Log Explorer creates a new task based on this template. You can also test a template without creating tasks. Click right mouse button on the template name and select Test template locally. This will run the task on your local computer.
