I found this info on how to view hidden files/folders in Linux:
When I booted to my USB Ubuntu I was not able to find an option to "View". I was able to use the "Ctrl H" option to view the hidden files. By doing this I was able to view & delete the files that were put on my computer by Linux with the "." hidden file indicator.
However, when I told Ubuntu to "Empty the trash" it did nothing. The "trash can" icon was still visually indicating that there was something in the trash. I shut down and removed my USB drive for Ubuntu and the files/folders on my Win7 with the "." as the first character were gone so that is now resolved. I am just wondering about the "Trash" that was left and not emptied.
