Strange text in etransmit txt file

[sirjoelsph]

I just did an Etransmit for a file with a few x-refs and at the very end of the file was this:

*** Map 2007 Data and Cache files ***

The drawing '{filename}.dwg' refers to a cache manifest XML file, zero or more cache files (.GWS) as well as raw data files.
Please ensure the manifest XML file and cache files are unzipped to the drawing directory or your current MapCache directory.
You may also need to update the cache manifest XML file to point to the unzipped location of the data files.

I don't remember ever seeing this before and I'm not quite sure what it means.  Anyone have any insight on what this might be?

Thanks.

I'll take a guess and say at one time the dwg or an xref in it came in contact with an FDO/Data Connection file. Even when you disconnect and delete the connection the .gws data is still there. It shouldn't cause any issues with the Etransmitted file(s).
