Step 1
Other our products Download FileMarker.NET. FileMarker.NET is similar to Folder Marker, but customizes files. FileMarker.NET is a handy tool that allows users to color-code files in Windows like in Mac and considerably simplify file management with the help of additional icons to display status, priority, completeness and type of data in a file. I have accidentally deleted all the contents on my iMac late 2012, with no CD Drive. The folder with the question mark has come up, and I have tried to put it in Recovery mode, Target Mode, and even had my hard drive attach to see if it could recognize the external hard drive. On your Mac, select the file or folder whose icon you want to use, then choose File Get Info. At the top of the Info window, click the icon, then choose Edit Copy. Select the other file or folder, then choose File Get Info. Click the icon at the top of the Info window.
Click the Finder icon in the Dock. A Finder window will open.
Step 2

The Info window of your home folder will open.
Step 3
Click the lock icon in the lower right corner and authenticate with the name and login password of an administrator on the system. If you have only one user account, you are the administrator.
Step 4
In the Sharing & Permissions section of the window, verify that you have 'Read & Write' privileges. If not, use the '+' and '-' buttons in the lower left corner to make the necessary changes.
Step 5
By default, the groups 'staff' and 'everyone' have 'Read Only' privileges. With those settings, the files at the top level of your home folder will be readable by other local users. You can change the privileges to 'No Access' if you wish, but then your Public and Drop Box folders will be inaccessible to others, and Personal Web Sharing won't work. Most likely, you don't need to change these settings.
Step 6
If there are entries in the Sharing & Permissions list for users or groups besides 'me,' 'staff,' and 'everyone,' delete them.
Step 7
Click the gear icon at the bottom of the Info window and select Apply to enclosed items... from the drop-down menu. Confirm. The operation may take several minutes to complete. When it does, close the Info window.
