+ 1. 扫描目录并计算哈希
+string[] directories = new[] { "path1", "path2" };
+var fileHashMap = new Dictionary<string, List<string>>(); // hash -> List<full paths>
+
+foreach (var dir in directories)
+{
+    foreach (var file in Directory.EnumerateFiles(dir, "*.*", SearchOption.AllDirectories))
+    {
+        using var stream = File.OpenRead(file);

+
+        fileHashMap[hash].Add(file);

+
+2. 将重复文件压缩并保存
+string archiveDir = "compressed_output";
+Directory.CreateDirectory(archiveDir);
+
+var manifest = new List<FileRecord>();
+
+foreach (var kvp in fileHashMap.Where(kvp => kvp.Value.Count > 1))
+{
+    var hash = kvp.Key;
+    var originalFile = kvp.Value[0];
+    var archivePath = Path.Combine(archiveDir, $"{hash}.gz");
+
+    using (var input = File.OpenRead(originalFile))
+    using (var output = File.Create(archivePath))

+    {
+        input.CopyTo(gzip);
+    }
+

+    {
+        Hash = hash,
+        ArchiveFile = $"{hash}.gz",
+        OriginalPaths = kvp.Value
+    });
+}
+
+3. 生成清单文件（JSON）
+public class FileRecord
+{
+    public string Hash { get; set; }
+    public string ArchiveFile { get; set; }
+    public List<string> OriginalPaths { get; set; }
+}
+
+File.WriteAllText("manifest.json", JsonSerializer.Serialize(manifest, new JsonSerializerOptions { WriteIndented = true }));
+
+
+4. 根据清单还原原始文件结构
+var manifestJson = File.ReadAllText("manifest.json");
+var manifest = JsonSerializer.Deserialize<List<FileRecord>>(manifestJson);
+
+foreach (var record in manifest)
+{
+    var archivePath = Path.Combine("compressed_output", record.ArchiveFile);
+
+    foreach (var path in record.OriginalPaths)
+    {
+        Directory.CreateDirectory(Path.GetDirectoryName(path)!);
+
+        using var input = File.OpenRead(archivePath);
+        using var gzip = new GZipStream(input, CompressionMode.Decompress);
+        using var output = File.Create(path);
+
+        gzip.CopyTo(output);
+    }
