InnoSetup - copy files before install

Question

How can we copy, move, rename user files before installation?

We can easily delete files using the [InstallDelete] section:

[InstallDelete]
Type: files; Name: "{app}\SomeFile.exe";

Can we do copy, rename in a similar way?

EDIT:

I tried to make this in [Files] section but I receive an error during compilation because source file does not exist:

[Files]
Source: "{app}\SomeFile.exe"; DestDir: "{app}\SomeDir\SomeFile.exe";

For copying files you can use the [Files] section, but I don't think there's a way for move or rename operations in a separate section, so I would suggest you to use [Code] section for this.

Here is a sample code for move and rename operations. They both use the RenameFile function as it is internally the same operation:

[Code]
procedure CurStepChanged(CurStep: TSetupStep);
begin
  if CurStep = ssInstall then
  begin
    // move file
    if not RenameFile(ExpandConstant('{app}\SomeDir\SomeFile.exe'), ExpandConstant('{app}\SomeFile.exe')) then
      MsgBox('File moving failed!', mbError, MB_OK);
    // rename file
    if not RenameFile(ExpandConstant('{app}\SomeFile.exe'), ExpandConstant('{app}\RenamedSomeFile.exe')) then
      MsgBox('File moving failed!', mbError, MB_OK);
  end;
end;
