Blue-highlighted folders &/or files can inherit next action.
Concerning deleting files accidentally, within Win 7 for sure, I’ve noticed right after copying or moving, the target folder’s new contents, and sometimes even copied or moved folders, often are “blue-highlighted,” and if I do not “remove” [click once anywhere in white space] the highlighting, the very next explorer.exe action may include those blue-highlighted aforementioned folders and/or files.
