How do I view the full path in search results?
The sort of view you're using just seems like a waste of space to me. Why not switch to Details view instead? That's what I use and I just add a path column when required.
To add a path column:
Right click the column header, select More...
Scroll down and check path.
I finally figured out that there are "Folder", "Folder path" and "Path" fields available.
Right-mouse-click over the "Folder" column heading to change columns that are displayed in the results and click "More..." at the menu bottom.
Scroll through available fields and check "Path" to activate it. Then uncheck the original "Folder" column.
DO NOT check the "Folder Path" column, because it will tell you the Path of the containing folder, in a similar way to the "Folder" column!
If it is just a single file, you can right click the file and open path location. Then, in the new location, click the explorer bar once and it will show the full path. However, that may become tedious if there are several files you want to check from the search results.
EDIT: Also, whenever I hover over the shortened path, it does display a tool tip of the full location. It only worked for me whenever my cursor was over the actual path text, ie C:\...\foo\...\bar. It did not work when I just hovered over the file in general.
