Reference
The image file name
Explanation
The FileName property refers to the filename of the image when the thumbnail image is selected. A thumbnail image can be selected using a mouse click, the keyboard, the SelectImage method, the SelectFile or MouseMoveOnThumb event. The filename of the image is retrieved by the SelectFile event when the thumbnail image is selected. For multi-page image files, the FileName property will have the page number appended to the end (If the page number is 0 then this is omitted).
Example: If the page number of ABC.TIF is 2 then the FileName property will contain the string, "ABC.TIF 2"
Note: if more than one thumbnail are selected at the same time, the FileName property will contain the filename of the last image in that group of selected images.
