MobileMe iDisk Help: Sharing specific files on your iDisk
You can share any file on your iDisk with anyone connected to the Internet. When you share an individual file, only the people to whom you give the URL to the file have access to it.
To share all the files in your iDisk Public folder with anyone who has access to it, see Related Topics below.
To share a specific file on your iDisk:
Select the folder or file you want to share.
If you want to share a folder or large file, it’s a good idea to compress it first.
Compressing or decompressing files
Click the Share File (or Share) button.
Whether you see a Share File or Share button depends on whether you’re viewing your MobileMe iDisk in column or list view.
To send an email with the URL to your shared items, enter the email address(es) in the Email Recipients field, and then type a message.
Keeping track of your shared files
If you want to require recipients to enter a password before being able to view or download the items you’re sharing, select the “Require password” checkbox and enter a password.
Important: Don’t give your MobileMe password to anyone. Others need only the shared file password to see the shared file.
If you want the URL to the shared item to expire so that no one will have access to it after a period of time, select the “Link expires after” checkbox, enter a number, and then choose a length of time from the pop-up menu.
Click the Share button.
If the selected item is already being shared, you can click Stop Sharing to stop the item from being shared any longer.
Give the shared file URL to the people with whom you want to share the file.
