+
+### 輸出檔案
+
+**dlgDumpLog.java (舊型號)**
+```
+./Log/{SN}_ControllerLog_{YYYY}_{M}_{D}_{H}_{m}_{s}.zip
+```
+
+**dlgDumpLog2.java (新型號)**
+```
+Primary: ./Log/Primary_{SN}_ControllerLog.zip
+Secondary: ./Log/Secondary_{SN}_ControllerLog.zip
+合併: ./Log/{PrimarySN}_{SecondarySN}_ControllerLog_{YYYY}_{M}_{D}_{H}_{m}_{s}.zip
+```
+
+### 壓縮前的暫存檔
+
+| Page Code | 檔案名稱 | 說明 |
+|-----------|----------|------|
+| 0x60 | EventPage.bin | Event Log |
+| 0x61 | DebugPage.bin | Debug Log |
+| 0x62 | DiskMetadataPage.bin | Disk Metadata |

+
+### compressLog() 流程 (dlgDumpLog2.java)
+
+```java
+// 單一控制器壓縮
+public void compressLog(String sSN) {
+    String prefix = sSN.equals(PageDataDB.sSN) ? "Primary" : "Secondary";
+    String filename = "./Log/" + prefix + "_" + sSN.trim() + "_ControllerLog.zip";
+    // ... 同上邏輯
+}
+
+// 雙控制器合併壓縮
+public void compressLog2() {
+    File[] logs = new File[2];
+    logs[0] = new File(sMaterFileNamePatch);  // Primary
+    logs[1] = new File(sSlaveFileNamePatch);   // Secondary
+    
+    // 合併成單一 ZIP，內含兩個 ZIP 檔
+    String filename = "./Log/" + PageDataDB.sSN.trim() + "_" 
+        + PageDataDB.sSlaveSN.trim() + "_ControllerLog_{timestamp}.zip";
+    // ... 
+}
+```
+
+### ZIP 結構
+
+```
+Archive: {SN}_ControllerLog_2024_3_29_10_30_45.zip
+├── EventPage.bin         (512 bytes/block)
+├── DebugPage.bin         (512 bytes/block)
+├── DiskMetadataPage.bin  (512 bytes/block)
+├── SpecialLogPage.bin    (512 bytes/block)
+└── TelMesPages.log      (40 bytes/record, 去除 null)
+```
+
+### 特殊處理：TelMesPages.log (Page 0x64)
+
+```java
+// 原始資料: 40 bytes/record，包含 null (0x00) 字元
+// 處理邏輯:
+// 1. 讀取每 40 bytes
+// 2. 跳過開頭的 null 字元
+// 3. 遇到換行符 (0x0a) 後，後續全部視為有效資料
+// 4. 輸出時每筆記錄加上換行符
+
+// Example:
+// Input:  [0x00, 0x00, 0x00, 0x31, 0x32, ..., 0x00, 0x00]
+// Output: "12...data\n"
+```
+
+### Java 類別使用
+
+```java
+import java.util.zip.ZipOutputStream;
+import java.util.zip.ZipEntry;
+import java.util.Calendar;
+
+// 關鍵類別
+ZipOutputStream zout = new ZipOutputStream(fout);
+zout.setLevel(5);              // 壓縮等級 (0=儲存, 9=最大壓縮)
+ZipEntry ze = new ZipEntry(filename);
+zout.putNextEntry(ze);
+zout.write(byte[] data);
+zout.closeEntry();
+zout.close();
+```
