Check Chris Willig's example
- and that could be made faster by aggressive increasing of the buffer
size (eg: Len := Len * 2 )

It should be both
- but even more important, it should not be obscure
- creating a TStringList when you want one long string is 'indirect'

Agreed

This is not meant to be personal, but I have noticed that a lot of
Delphi coders are not really that familiar with working with Strings.
- because they are really a fairly recent addition to the language

Where you would use a TStringList I would probably use a dynamic array
or just one long string.

Obviously, I have a large library of string manipulation routines that
started life well before Delphi - in DOS BASIC and ASM
