Created my very first e-book sample. (Yeah!!!) There's not much to brag about, but I learned something new about file paths! When I tried to get the viewers (such as LibreOffice) accepted as alternatives to the default setting, the system didn't offer any paths to .exe files. I kept reaching a dead end. Until I found out -- here comes the exciting bit -- the ending is .bin (!) and the file paths are best found by looking in the Task Manager (Windows)!
