Before editing: Empty : nothing in it Full: only one folder in it Full2: 1 non-folder file in it Full3: 2 non-folder files in it <*spoiler*>by changing registry value: <*/spoiler*> After editing: Only the Empty folder icon gets changed. For any other types of folder icon, they are not changed. Conclusion: The windows folder icon is dynamic. Rather than changing itself from "image" to "image", it actually "deviants" itself with the file inside. And I really do not want to turn off thumbnail view for folders...... Question: 1, How can I make the other 3 types of folder change as well? since the folder doesn't actually change if you look carefully. They just got overlaid by those thumbnails. 2, Where can I find information about how the folder icon works(or thumbnail works)? I am sure that it is not as simple as changing the icon entirely when a folder is made/modified. Specs: -Thanks for reply
