When I opened up a VS solution this morning, the icons for files in the data folder had changed. They normally look like (a slightly different folder):
They now look like:
What does that icon mean, and how could I possibly find this out (apart from posting this question, hopefully)??
Motivation: The issue is that these files are used as upload files in web tests, and are now all failing with "Request failed: Could not find a part of the path" even when I add them to the path, and I am absolutely certain that the paths are correct (copied the path from the file properties).
Anything at all that I could try would be hugely appreciated.
