Duplicated Thumbnails - My Solution

Apologies if this has already been covered. I did try searching the forums for a solution but in the end the problem was with my pc not serviio.

My problem was that in one of my folders (Only this folder) the art work for different video files was showing as the same thing.
I tried deleting the offending file from folder {Didn't do anything}
I tried from the Console - Metadata - Rescan video Metadata {Didn't do anything}
I tried deleting (thumbnails.data & thumbnails.key) from C:\Program Files\Serviio\library\cache {Didn't do anything}
I noticed when I browsed to the folder in windows it also had the offending artwork in the folder icon.

My Solution
Stop Serviio and close console
Go into the folder using the default file browser
Click "Organise" - "Folder and Search Options" - "View" tab - tick "Show hidden files, folders and drives" and untick "Hide protected operating system files" - OK
You should see a thumbnail file and hopefully your offending .jpg artwork. Delete them.
Click "Organise" - "Folder and Search Options" - "View" tab - untick "Show hidden files, folders and drives" and tick "Hide protected operating system files" - OK
Restart Serviio.

The artwork was now correct for different video files.

I am running Win 7 64Bit and Serviio Pro 1.4.1.2
I have a BT Hub and an LG 47LM620T
