(Or just set the hidden+system attributes on the file. You can tell Opus to hide it by name as well using Folder Options, if you want.
Explorer must have a hardcoded filter on autoexec.bat by name whereas, by default, Opus only hides it if it has the hidden+system attributes set. If that installer didn't set them to be hidden then they won't be.īy the way, I just tested creating an autoexec.bat file in my C:\ and it seems that Explorer filters that file out even if it isn't hidden. The only way you'd get them is if something created the files, probably an installer. On a default install of recent versions of Windows you shouldn't have an autoexec.bat or config.sys. Not in Explorer, Opus or a DOS prompt, even if hidden/protected files are shown.
When I say they don't exist on my system I mean they really don't exist.
