This video is an introduction to the Blade user interface.  It shows how to select your source image or file and how to select an export folder.  The video also gives an introduction to the Global/Personal Signature Databases.  In the demonstration, a simple JPEG header is added to the Personal Database and an Encase image is selected for recovery.  With multi segment images, you only need to select the first image (i.e. *.e01, *.s01, *.000 or *.001), Blade will automatically identify all the required segments.
