Summary

This article describes previous local iDisks files or folders that may be located on your desktop, and some of the issues you should be aware of when dealing with them.

The previous local iDisk file contains all of the files and folders that were copied down from your MobileMe iDisk, as well as any files you had copied to your local iDisk: 

  • In Mac OS X v10.6 and v10.5, the previous local copy is named yourMobileMeMembername.sparseimage.
  • In Mac OS X v10.4 and earlier, the previous local copy is named yourMobileMeMembername.dmg.

Examining the contents of the previous local iDisk file

First open the file by double-clicking it. This will cause a plain white disk image icon, named after your MobileMe member name, to appear on your desktop. Then open that file (disk image) and look through it for any files that you want to keep. Be sure to examine the following locations:

  • The root level of the disk image and any custom folders you may have created there
  • Documents and its sub-folders
  • Movies and its sub-folders
  • Music and its sub-folders
  • Pictures and its sub-folders
  • Public and its sub-folders
  • Sites and its sub-folders

Make sure to copy any important files from the disk image by dragging them from the plain white disk image to your desktop. After you have completed copying any files you wish to save, be sure to back them up using your usual strategy.

Additional Information

After you have copied data from the disk image that you want to keep, you can keep or delete the previous local iDisk fileThe previous local iDisk can take up a large amount of space depending on what version of Mac OS X you are using. However, it can also serve as an easy backup file, so you may want to keep and move it to another location that is large enough to store it easily.
