Hidden thumbnail file
So for the first time I tried using Azardi to validate an epub file I am working on. Everything was checking out except that it was saying that there were files in the package that were not in the manifest. For the life of me I could not find such an error in the code. Finally I copied all files into another folder and than rebuilt the entire book file by file. When I was done it worked without my having changed a line of code. It was then that I realized that the extra file that the Azardi ouput was stating was not in manifest was the invisible file that Windows XP creates for a folder when the view format for the folder is set to thumbnails. This is my standard OP for folders containing only images. Once this is done for the folder the file is there but invisible and does not go away even if the folder view choice is set to something other than thumbnails.
I just thought I would mention this to any out there who might not be aware of the issue.
