The Problem
Today, when I use Winmerge's shell integration to compare tow folders, Winmerge just lists files and folders in the first layer, and the tree mode is disabled(grayed out).
The Solution
I can click ctrl+O or click File -> Open to open the "Select Files or Folders" dialogue, this will fill the Left and Right with current value, then I can the mode to "Include Subfolders", then change to Tree mode.
Another way is to: press(hold) Control(ctrl) button while selecting(clicking) the WinMerge or Compare.
This will include subfolders when compare tow folders.
Another way is to go to "Edit" -> "Options", go to "Shell Integration", check "Enable Include subfolders by default".
Personally I like the previuos solution better(press ctrl button).
