Lost .frm files

[Sujay Koduri]

I have changed the OS on my database server. At that time, I forgot to take
the backup of the .frm files in /var/lib/mysql. I have taken all the backup
of all the data files.
I can recreate all the tables. How can I map these tables to existing data
files. Is this possible. Please help me out as the data is huge. (alomost

Thank you
