I activated the "Show hidden files" checkbox in the options but the only way I can access subfolders is through the "thumbnail window".
This is rather unpractical if I want to move files and have to many files inside a folder to see the file to move and the subfolder on one screen. In this case one has to be really quick or open a second XnView window.

(I use XnView 1.82.4 on Windows XP SP2)
