A lot of my file icons have become transparent and I cannot access them with some programs and applications. For example they don't show up on my quick launch task bar but they are in the quick launch folder. More annoyingly I'm trying to build a website and the files that are 'transparent' don't show up in the web builder so I can't use images etc in my design. I've tried copying the contents of the file and renaming them but there still transparent. It also seems quite random which are and are not. Some newly created files are and others aren't ditto older ones. It even seems to affect files in my external hard drive. I've tried Google but to no avail.
