Imagine there are two win.ini files and I want to combine both together. Some of 
the common sections and keys/ values are the same in each but they differ in their 
data generally. How could I merge the two together to get an ini file that contains 
all the data from both in the right places?

Answer:

Iterate over the sections in the source file. For each section, iterate over the 
names. If there is a name in Source that already exists in Dest, Dest's copy will 
be overwritten.

1   { ... }
2   var
3     Source, Dest: TIniFile;
4     SectionNames: TStrings;
5     i: Integer;
6   begin
7     SectionNames := TStringList.Create;
8     try
9       Source.ReadSections(SectionNames);
10      for i := 0 to SectionNames.Count - 1 do
11      begin
12        MergeSection(Source, Dest, SectionNames[i]);
13      end;
14    finally
15      SectionNames.Free;
16    end;
17  end;
18  
19  procedure MergeSection(Source, Dest: TIniFile; const SectionName: string);
20  var
21    i: Integer;
22    Section: TStrings;
23    Name, Value: string;
24  begin
25    Section := TStringList.Create;
26    try
27      Source.ReadSection(SectionName, Section);
28      for i := 0 to Section.Count - 1 do
29      begin
30        Name := Section.Names[i];
31        Value := Section.Values[Name];
32        Dest.WriteString(SectionName, Name, Value);
33      end;
34    finally
35      Section.Free;
36    end;
37  end;
