我的安装程序的大小可以降低吗？
目前，我的GoogleAuthAndSync支持实用程序的代码已经存在：
; Google Calendar Interface v3
Source: "Google.Apis.Auth.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.Auth.PlatformServices.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.Calendar.v3.dll"; DestDir: "{app}"; Flags: ignoreversion

Source: "System.Net.Http.Primitives.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Zlib.Portable.dll"; DestDir: "{app}"; Flags: ignoreversion
如您所见，这些文件已安装到{app}文件夹中。我没有使用外卡的原因是因为我也有语言资源dll文件，并且不想包含它们。
然后，我将OutlookCalIFConsole实用程序安装到子文件夹中：
; Outlook Calendar Interface
Source: "OutlookCalIFConsole\*.dll"; DestDir: "{app}\OutlookCalIFConsole"; Flags: ignoreversion
Source: "OutlookCalIFConsole\OutlookCalIFConsole.exe"; DestDir: "{app}\OutlookCalIFConsole"; Flags: ignoreversion sign
Source: "OutlookCalIFConsole\OutlookCalIFConsole.exe.config"; DestDir: "{app}\OutlookCalIFConsole"; Flags: ignoreversion

许多DLL文件现在都是相同的日期等。那么，有没有办法只将受影响的文件添加到安装程序中并部署到两个位置？
我不想过度复杂化或导致自己出现维护问题。
请注意，我还设置了SourceDir指令：
[ISPP]
#define SourceDir "..\Meeting Schedule Assistant\Release"
[Setup]
SourceDir={#SourceDir}

您可以使用预处理器迭代子文件夹中的DLL文件，并将它们与基本文件夹中的文件进行比较。如果匹配，请使用基本文件夹中的文件作为源。 Inno Setup将compile a source file only once to the installer, when used multiple times。
使用SourceDir指令（预处理器显然不知道）的代码有点复杂。没有指令，代码会更简单。
[Files]
#pragma parseroption -p-
#define FileEntry(Source, DestPath) \
"Source: " + Source + "; DestDir: " + DestPath + "\n"
#define GetFileTimestamp(Path) GetFileDateTimeString(Path, 'dd/mm/yyyy hh:nn:ss', '-', ':')
#define ProcessFile(RootPath, Path, AlternativePath, DestPath, FindResult, FindHandle) \
FindResult ? \
Local[0] = FindGetFileName(FindHandle), \
Local[1] = AddBackslash(Path) + Local[0], \
Local[2] = AddBackslash(AlternativePath) + Local[0], \
Local[3] = AddBackslash(RootPath) + Local[1], \
Local[4] = AddBackslash(RootPath) + Local[2], \
Local[5] = \
FileExists(Local[4]) && \
(GetFileTimestamp(Local[3]) == GetFileTimestamp(Local[4])), \
FileEntry((Local[5] ? Local[2] : Local[1]), DestPath) + \
ProcessFile(RootPath, Path, AlternativePath, DestPath, \
FindNext(FindHandle), FindHandle) \
: ""
#define ProcessFolderWithAlternativeSource(RootPath, Path, AlternativePath, DestPath) \
Local[0] = FindFirst(AddBackslash(AddBackslash(RootPath) + Path) + "*.dll", 0), \
ProcessFile(RootPath, Path, AlternativePath, DestPath, Local[0], Local[0])
#pragma parseroption -p+
#emit ProcessFolderWithAlternativeSource( \
"..\Meeting Schedule Assistant\Release", "OutlookCalIFConsole", ".", \
"{app}\OutlookCalIFConsole")
或者您可以使用SetupSetting来阅读SourceDir指令：
#emit ProcessFolderWithAlternativeSource( \
SetupSetting("SourceDir"), "OutlookCalIFConsole", ".", "{app}\OutlookCalIFConsole")
如果你add SaveToFile to the end of the script：
#expr SaveToFile(AddBackslash(SourcePath) + "Preprocessed.iss")
...那么你应该在Preprocessed.iss：
[Files]
Source: OutlookCalIFConsole\CommandLine.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\Microsoft.Graph.Core.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\Microsoft.Graph.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\Microsoft.Identity.Client.dll; Dest: {app}\OutlookCalIFConsole
Source: .\Newtonsoft.Json.dll; Dest: {app}\OutlookCalIFConsole

Source: .\System.Security.Cryptography.Primitives.dll; Dest: {app}\OutlookCalIFConsole
Source: .\System.Security.Cryptography.X509Certificates.dll; Dest: {app}\OutlookCalIFConsole
请注意Newtonsoft.Json.dll，System.Net.Http.dll和System.Security.Cryptography.*的条目。
您可以使用GetFileDateTimeString（因为文件是DLL），而不是按GetFileVersion（间接通过GetFileDateTimeString）比较文件。
如果您需要[Files]部分条目中的其他参数，请相应地修改FileEntry宏。

我找到了允许InnoSetup编译器在压缩过程中成功对文件进行重复数据删除的解决方案，我的配置中有趣的部分是：
Compression=lzma2/ultra64
LZMANumBlockThreads=4
CompressionThreads=4
LZMADictionarySize=262144 ; this allows to find duplicated files and succesfully deduplicate them (but compressor consumes up to 2.5GB / ram during compilation)
LZMAUseSeparateProcess=yes
SolidCompression=yes
InnoSetup版本为6.0.2（u）
