The files that are needed for the tests/labs in GMetrix are copied and created into the GMetrixTemplates folder during the test. The GMetrixTemplates folder will remove itself when you exit a test/lab, so the folder and files only exist during a test/lab.
The default location for the GMetrixTemplates folder is in C:\USER\Documents.
If students change computers, they will want to go into Local User Settings and ensure the settings are correct for the new computer. We recommend students always check their Local User Settings before starting/resuming and GMetrix tests to ensure that the Templates folder is set to the desired file path.
