The file you just unzipped contains four files: This readme.txt file,
SW-Content-Register-KSDK-1.0.0-Beta-FreeRTOS.txt, 
FreeRTOS and Kinetis SDK Integration Notes.pdf
and another ZIP file contain the actual RTOS kernel code. Please
follow the instructions below to unzip the RTOS kernel code to the
right place.

The instructions here assume you have the KSDK installed in
"C:\Freescale\KSDK_<version>". There is a folder named "rtos" at
"C:\Freescale\KSDK_<version>\rtos", which contains a set of sub
folders:
   * mqx:      The designated folder for Freescale MQX kernel code
   * FreeRTOS: The designated folder for FreeRTOS kernel code
   * uCOSII:   The designated folder for uC/OS-II kernel code 
   * uCOSIII:  The designated folder for uC/OS-III kernel code

Please unzip the FreeRTOS kernel code ZIP file to the folder
"C:\Freescale\KSDK_<version>\rtos\FreeRTOS".  Then right click the
file; it will bring up a popup menu. Select "WinZip", and then select
"Extract to here" to unzip the RTOS kernel code. 

When done, you can build and run the demo "I2C Demo with RTOS" to
verify the functionality. Please refer to the Kinetis SDK Demo
Applications User Guide for details about the demo.

You may have other ways to unzip the RTOS kernel code; the key is not
to create an additional sub folder in the FreeRTOS folder when doing
the unzipping.
