I use my machine primarily for image editing of very large
files. Even in list and details view, Explorer is reading
each file and caching its thumbnail. (I can switch between
views and see this happen.) That not only causes
responsiveness problems, but also gives me a file in use
error if I try to do anything with groups of files before
all the thumbnails are crated.
I'd be happy if I could turn off all thumbnail activity. I
have other software for image management.
