  A folder failed to be moved. On Windows this typically means that a program is using that folder (for example Windows Explorer or your anti-virus software.)
  Please momentarily deactivate your anti-virus software or close any running programs that may be accessing the directory 'E:\android_sdk\tools'.
  When ready, press YES to try again.
  Note: you can use --force to override to yes.
