I'm trying to make the \documentsettings\user\temp folder as read only to prevent files from writing files into it ( I have reasons to do so). But I've tried all the basic methods of doing so, from the command line using +R on the folder, but it refuses to stay in the read only mode. Basically what I'm trying to achieve is to prevent files being created on the temp folder. I don care about applications that would crash if it was denied access into it. In fact, I am testing what applications crash on making it read n
The read-only property on folders (+R) does not do what you think on windows. See http://support.microsoft.com/kb/812003
To truly make a folder read-only you need to be on a NTFS file-system and set the permissions on the folder instead which appear under the Security tab (right-click the folder and choose Properties from the menu then select the Security tab). Remove the Modify and Write permissions of each users and group listed from the folder and then no one will be able to write to it.
You may have to click Advanced > Change Permissions and uncheck "Include inheritable permissions ... " to clear SYSTEM permissions that are often inherited from the parent.
