Cannot save in publisher

[Ciar?n]

I have copied some publisher files from a network to a local drive.
When i open these files and click save I get the following message

The disk you are trying to save to is write-protected. make the disk
read/write or use a different disk.

I've looked at both the folder and the file.
Neither are read only
In security Everyone has full control
All domain users are administrators on the PC
Excel and word document in the same folder which were copied in the
same way do not give any problems.
If i change the filename it saves to the destination folder without
issue.

What is the problem with either publisher or the permissions set on
the file?

This sounds like a network issue of some type, as you say changing the file
names it allows the files to be saved.
I would say there are links in those files of some type, and as soon as you
change the file name the links are broken.

This is definitely not a Publisher issue or a known problem.
