Iris.dat and upload to iris community Edition

Have a iris.dat file that was zipped in axis but , now I unzipped it and can see the file in my c drive but when I go to iris management console to perform a new db to pull in the current iris.dat file , in the wizard I do not see the iris.dat file listed.

Need some help with getting it restore the Cache backup in my iris community edition. 

thank you,
