I recently received a comment on one of my previous posts about the program Folder Menu. I had actually been meaning to post about it – it currently seems to be the best 64-bit replacement for Folder Guide. It is relatively simple to use, and seems to work in all dialog boxes.
Basically, middle button on the mouse brings up the menu, left-click to ‘navigate’ folders within the menu, right-click to actually Explore a folder. If you want to always just Explore using left-click, change the Use browse mode when capslock is off option on the ‘Menu’ tab of the Options.
Give it a go and feel free to post your comments.
