When moving files from the CD-ROM to your computer, the files will be locked, and you will not be able to modify them until they have been unlocked. Unlocking the files is easily done. Following are instructions for unlocking files on a PC or a Mac.
To unlock files on a PC:
1. Open Windows Explorer.
2. Find the file you wish to unlock.
3. Right-click on the file.
4. Click on "Properties" at the bottom of the menu.
5. Uncheck the "Read-only" checkbox in the "Attributes" section at the bottom of the page.
6. Click "OK".
A shortcut to unlocking files is to unlock an entire folder at once. Follow the above steps by clicking on the folder instead. After step 5, select "Apply changes to this folder only." Then, follow step 6 and click "OK." This will unlock all the files in the directory.
To unlock files on a Mac:
1. Drag the files you wish to unlock to your Desktop.
2. Highlight the files you wish to unlock. (You cannot highlight entire folders and unlock them, but you can highlight many files to unlock simultaneously.)
3. Go to the File menu from the Desktop.
4. Select Get Info / General Information.
5. Click on the Locked box at the bottom left-hand side of the screen. If this box is checked, then the file is locked.
