The TestComplete Test Visualizer captures images of your tested application for operations performed during test recording and playback. These images, as well as other helper Test Visualizer files, are stored in the Visualizer\<TestName>_<TestExtension> subfolder of the folder containing your test. Here, TestName is the name of your test as you see it in the Project Explorer panel, and TextExtension is the extension of the test file on the disk (see Project and Project Suite Files for possible extension values).
When you rename a test, TestComplete also renames the folder containing the Test Visualizer data for the test. Likewise, when you save the test to another location, TestComplete moves the folder with the Test Visualizer data to the appropriate location.
This message appears when TestComplete is unable to move a specific Visualizer file. For example, the problem occurs if this file is locked by another application. In this case, TestComplete leaves the file in its original location. Note that if the problematic file is an image, this image will be unavailable in the Test Visualizer panel, as the image’s location on the disk no longer corresponds to the test file location.
