I am trying to figure out how to write the following code:

I would like to have a dialog box open and the user pick the location
of a .txt file. This .txt file will have the full path of numerous
excel files. I would like the script to

1. open every file listed in the .txt file, until they are all open at
the same time
2. save all the files that were opened
3. close all the files that were opened

Then I would like to generate a .txt file in the following location C:
\Model that lists all the files that were opened and saved during the
run of the procedure and the date and time that they were saved.

I haven't been able to figure this out. Can someone help with a
solution?

Thanks,

Joshua
