# 是否檢測上傳文件已經存在。假設已經存在,則不存在文件內容,創建一個符號連接以節省磁盤空間。
# 這個應用要配合FastDHT 使用。因此打開前要先安裝FastDHT
# 1或yes 是檢測,0或no 是不檢測

# 如下是關於FastDHT servers 的設定 需要對FastDHT servers 有所瞭解,這裏僅僅說字面意思了
# 可以經過 #include filename 方式來載入 FastDHT servers 的配置。裝上FastDHT就知道該怎樣配置啦。
# 相同要求 check_file_duplicate=1 時才實用。否則系統會忽略

# pure filename, the base path is the base path of current/this config file.
# must set FastDHT server list when check_file_duplicate is true / on
