Problems with opening of files MC14

[VladimirN]

Hello!

I can not open the given files for Mathcad 14 (links to files are taken from a subject here ( http://blogs.ptc.com/bid/38099/Mathcad-in-Textbooks-Elements-of-Optical-Networking ) :

"Mathcad in Textbooks: Elements of Optical Networking"

Somebody else tried to open these files?

I couldn't open them either.

I can't open them from the link either, so I'll ask the person who posted them to repost them.

Thanks, Alan and Mona!

I hope that links will be corrected.

I think they are PK zip format (well those are the first two letters in the file, the file name .xmcd is a few bytes further on)

I'm guessing it is a PKsecure http://www.pkware.com/downloads/ zip file.

Yes, they are password protected zip files. I didn't realize there was any question about that. I use PeaZip, and it quite happily tries to open them. But it asks for a password, which of course I don't have.

Attached are the files from Elements of Optical Networking.

Let me know if you still can't open them.

They both open fine for me.

[AlanStevens]

Yes, they both open ok for me now as well.

Thanks. Now all works fine.
