TestComplete samples (both built-in and additional) are located in the <Users>\Public\Public Documents\TestComplete 15 Samples folder.
Some file managers display the Public Documents folder as Documents.
The Test Log sample illustrates working with the TestComplete test log from scripts: posting a variety of pictures and messages to the test log and organizing them as a hierarchy of folders.
This sample is a part of the additional sample package. To use it, download this package from support.smartbear.com/testcomplete/downloads/samples and install it.
