The damage files vary from a couple of lines, to a sheet or two, to dozens, if not hundred. The drawings are often with the text, but occasionally separate. The way that the TNARO works you would need to know which pages/sheets to ask for.
I have not looked at Exeter's files, but did look at York's file for the time after she had been beached. That was impressive as they were looking at ways of salvaging her. A full set of large drawings (about 4 foot long) with many details. However, the files for the severe damaging (not "sinking") of Queen Elizabeth and Valiant are about 60-70 pages of text with only small diagrams.
IF you have a friend who visits best to get him to have a look.
Exeter's post-action report is very detailed.
At the TNARO the info can be in one file, or scattered through several (sometimes not specifically mentioned in the document title).
