InnoSetup-安装前复制文件 [英] InnoSetup - copy files before install

问题描述

在安装之前，我们如何复制，移动，重命名用户文件?

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

我们可以使用[InstallDelete]部分轻松删除文件:

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

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

我们可以用类似的方式复制，重命名吗?

Can we do copy, rename in a similar way?

我试图在[Files]部分中做到这一点，但由于源文件不存在，因此在编译过程中收到错误消息:

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"; 

推荐答案

要复制文件，您可以使用[Files]部分，但是我认为没有办法在单独的部分中进行移动或重命名操作，因此我建议您使用[Code]部分.

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.

这是移动和重命名操作的示例代码.它们都使用 RenameFile 函数，因为它在内部是相同的操作:

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;
