First - you would not be restoring the files "in Works" - as that is just an
application that allowed you to view the file format the saved files were
in.
Second - you stated "a while back". While there is a possibility these
files might still exist - intact - on your system to be recovered.. every
second of actual use since their deletion has lessened that possibility
exponentially. If your definition of a "a while back" is anything similar
to mine - those files are FUBAR.
