File recovery

Had to reboot computor and when i did a restore all the files have an endind of .dcm

and nothing will open. Is there something that  i can do. Thanks

Can u please be more specific on the process of wat u did like before and after reboot?

what were you using to do the restore?  Windows restore? 

yes i did

I re booted hard drive with restore disks  then I used windows recovery to pull files from my book

You can do further google searches for .dcm files, but this is what I came up with so far.
