語法：IF EXIST 檔案路徑 (Action 1) ELSE (Action 2)
程式碼範例：
::Step1:定義變數(資料夾or檔案路徑)set MydirPath=”D:\BLOG\MyDir”set MyfilePath=”D:\BLOG\MyFile.txt”set NotExistFilePath=”D:\BLOG\NotExistFile.txt”
::Step2:由路徑檢查資料夾or檔案是否存在IF EXIST %MydirPath% (echo dir”MyDir” exist) ELSE (echo dir”MyDir” not exist)IF EXIST %MyfilePath% (echo file”MyFile” exist) ELSE (echo file”MyFile” not exist)IF EXIST %NotExistFilePath% (echo file”NonExistFile” exist) ELSE (echo file”NonExistFile” not exist)pause
！注意事項：
- ::(statement) 表示該行為註解
- 定義變數格式：set name=value，等號前後不能有空格，錯誤示範：set MydirPath = “D:\BLOG\MyDir”
- IF EXIST要搭配使用，不能單獨使用EXIST
- 最後要加上pause指令，否則cmd執行完畢會自動跳出，無法觀察output
Test Case：
D:/BLOG路徑下存在 MyDir & MyFile.txt，不存在NotExistFile.txt
