I get 11249 images per class if I ignore Thumbs.db and the zero-size images

Each folder has 11251 files, if you ignore the zero-size file (as the instructions say to) that makes 11250 files, but I think you should also ignore Thumbs.db as this is a Windows cache file, but this brings the number down to 11249.

The expected output in the notebook says 11250.

Shouldn’t it be 11249? Is this a mistake in the assignment?

Does this help?
