     <string name="faq_11_text">當然，只要在縮圖瀏覽中使用[歸類]選單項目就可以了。你能依多種條件歸類檔案，包含拍照日期。如果你使用了[資料夾內容全部顯示]功能，你還能以資料夾來歸類。</string>

     <string name="faq_12_text">那很可能是由於檔案從某處複製過來所造成的。你可以選擇檔案縮圖，然後選擇\"修復拍照日期數值\"來進行修復。</string>

     <string name="faq_11_text">Sure, just use the \"Group by\" menu item while at the thumbnails view. You can group files by multiple criteria, including Date Taken. If you use the \"Show all folders content\" function you can group them by folders too.</string>
