I have an Encrypted USB pin drive. I need to change permissions in the folder and file in such a way that they are no read-only. I use Windows 7 and when I click Properties, for that drive I see a checkbox that is selected by default. If I un-check it, click Apply and then Save it seems that the new settings take place only to open the Properties again to see that the Read-Only setting is still set by default. And yes, when I click Apply I am asked if i want to apply to the directory and all files, which I do confirm.

What am I missing and how can I change this?enter image description here

When you are editing these settings do you have the drive unlocked? – DiscoveryOV Jun 19 '12 at 3:38
Yes, I have to login before I can even access the drive. – usabilitest Jun 19 '12 at 3:53
Was it read only before you encrypted it? – DiscoveryOV Jun 19 '12 at 3:55

That partial read-only setting appears on pretty much every folder that contains a desktop.ini file, as I understand it. You will see the same thing on your hard drive.

It just means that (at least) one file in that folder is read-only, most likely desktop.ini.

The "read-only" check box is referring to the read-only file attribute. That is the reason you can not apply it on a directory, only on the files in a directory. Therefore on a directory you will never see the read-only checkbox in checked state that is only possible on files. This flag is also set if any file contained in the directory is marked as read-only.

BTW: Some USB sticks have an hardware read-only switch. That may be an alternative that can not be simply removed by software.
