File changes

Hi,
We had a Mixed network. Novell 4.11 and NT 4.0. ON the network we have some Macintosh operators who use graphic file and have been saving them to the Novell servers.

Over the weekend, we did a full migration from Novell to Windows 2000 servers. All files copied okay.

Problem: Now the Macintosh users, when they access their graphic files, find that the files have been changed / converted to PC files and they are unable to open them.

We still have the Novell Servers, they are currently shut down. I really do not want to bring them back up. Is there any way that those ‘converted’ files can be changed back to Mac files for their Adobe applications?

Thanks.
