This is a weird question, but I've been trying to figure out how to CREATE a "protected operating system file/folder." For example, "desktop.ini" is one.
My story is that I accidentally deleted a junction (the C:\Documents and Settings junction which maps to C:\Users for backwards compatibility). I created a new one using the command-line mklink tool, but the folder is not marked as a "protected operating system file", so when I turn the option on to hide those, it still shows up.
The only thing I can find online that is special about these files is that they have the System and Hidden attributes both turned on. I have turned these on, but it still shows up, so there seems to be another flag behind the scenes that marks files as "protected" files.
Any search turns up a million tutorials for how to go into the Folder Options GUI and turn on/off the "show..." option. Does anyone know how to do this? Let me know if I need to elucidate.
