Mapping table of *.DAT files to symbol / security name required.

[Garenaud]

Good day,

Is there any way of obtaining a mapping table of my *.DAT files to the
underlying Symbol or Security name for the data it contains? I don't
mind constructing this table manually if that is the only method. I
had a quick look inside the Master file but that is binary and I have
no knowledge on how to access it.

Any advice gratefully received.

Steve
