How to clear file system cache (timer cache) in SharePoint servers?

  1. Stop the Timer service through the Services console.
  2. On the computer that is running Microsoft Office SharePoint Server 2007 or SharePoint Server 2010 and on which the Central Administration site is hosted, open Windows Explorer, locate and then double-click the following folder:

    Drive:\Documents and Settings\All Users\Application Data\Microsoft\SharePoint\Config\GUID
    [For Windows Server 2008, the folder location is, Drive


    • The Drive placeholder specifies the letter of the drive on which Windows is installed. By default, Windows is installed on drive C.
    • The GUID placeholder specifies the GUID folder.
    • The Application Data folder may be hidden. Show hidden files and folders through Windows Explorer’s Folder Options setting.
  3. Back up the Cache.ini file.
  4. Delete all the XML configuration files in the GUID folder. Do this so that you can verify that the GUID folder is replaced by new XML configuration files when the cache is rebuilt.

    Note When you empty the configuration cache in the GUID folder, make sure that you do not delete the GUID folder and the Cache.ini file that is located in the GUID folder.

  5. Open the Cache.ini file in a text editing program.
  6. Delete everything in the file and type 1.
  7. Save and close the file.
  8. Start the Timer service through Services console.

    Note The file system cache is re-created after you perform this procedure. Make sure that you perform this procedure on all servers in the server farm.

  9. Make sure that the Cache.ini file in the GUID folder now contains its previous value. For example, make sure that the value of the Cache.ini file is not 1.
  10. Open SharePoint Central Administration site and verify that the Config Refresh entry is Succeeded in the Timer job Status.
