The question seems very simple.
I have a folder in a USB drive and I want:
1) to make it non-readable
2) to make it readable but non-executable
Now, if you google there seems to be a lot of pages with the apparent solution. However they all go "Right click the folder, and select settings. Then select the Security tab…"
I can do that with folders in my C: drive.
I can not do that with folders in my removable USB drive. The security tab does not exist.
How can I do the things I posted above?
