[p4] change filetypes for whole subtree?

[William Deegan]

Greetings,

I used cvs2p4 and it created all the files as type ktext, which I'd
like to undo.
Can I change all the files back and get the original $Id $ values
which were imported?
I want to verify the cvs checked out files match the perforce checked
out imported files,
and of course since the $Id $ is getting expanded all files are
showing differences..

Thanks,
Bill
