When you are trying to access a file or folder on your computer, then mySCC will ask for permission for that access (see below). "Read Access" lets you view files and folders; "Full Access" lets you view, open, modify and save changes to those files. (On the Macintosh, it's two separate messages: one for READ access, one for WRITE access.)

If you choose the “Never ask me again” option and need to change your mind, then double-click on the “Program Neighborhood Connection Center” icon in the system tray (lower right corner of the screen). From the pop-up menu, click on the “File Security” button to bring up the following dialog box and make the appropriate change.
