Certain files greyed out in Finder

I did a Get Info on one normal file and the disting file but can't see a meaningful difference. I can only find disting file when doing a search in a finder window, and it loads up just fine in Preview. This is happening for many other files as well not just disting. This 'manuals' folder is on an external hard drive fwiw. Anyone know what's up?
