Corruption of the Offline Files cache.

The Offline Files cache is a folder structure located in the %SystemRoot%\CSC folder, which is hidden by default. The CSC folder, and any files and subfolders it contains, should not be modified directly; doing so can result in data loss and a complete breakdown of Offline Files functionality.

  1. In Folder Options, on the Offline Files tab, press CTRL+SHIFT, and then click Delete Files. The following message appears:


    The Offline Files cache on the local computer will be re-initialized. Any changes that have not been synchronized with computers on the network will be lost. Any files or folders made available offline will no longer be available offline. A computer restart is required.

    Do you wish to re-initialize the cache?


  2. Click Yes two times to restart the computer.
