使用.bat文件检查文件夹是否存在[closed](Checking if a folder exists using a .bat file [closed])

使用.bat文件检查文件夹是否存在[closed](Checking if a folder exists using a .bat file [closed])

我想要检查某个文件夹（FolderA）是否存在，如果是，则显示一条消息，然后退出批处理文件。

如果FolderA不存在，我想检查另一个文件夹（FolderB）是否存在。 如果FolderB不存在，应该显示一条消息并创建文件夹，如果FolderB存在，则应该显示一条消息。

有人有任何想法的代码，我可以简单地使用记事本创建一个批处理文件，以允许我这样做？

所有这一切都需要在一个.bat文件中完成。

I would like to be able to check if a certain folder (FolderA) exists and if so, for a message to be displayed and then the batch file to be exited.

If FolderA does not exist, I would then like to check if another folder (FolderB) exists. If FolderB does not exist, a message should be displayed and the folder should be created, and if FolderB does exist, a message should be displayed saying so.

Does anybody have any idea on the code I could simply use on notepad to create a batch file to allow me to do this?

All of this needs to be done in one .bat file.

尝试使用这个文件：

IF EXIST yourfilename ( echo Yes ) ELSE ( echo No )

用你的文件名替换你的文件名。

对于dir，请看http://support.microsoft.com/kb/65994

C: IF NOT EXIST C:\WIN\NUL GOTO NOWINDIR CD \WIN :NOWINDIR

Try using this for a file:

IF EXIST yourfilename ( echo Yes ) ELSE ( echo No )

Replace yourfilename with what you file name is.

For a dir look at this https://jeffpar.github.io/kbarchive/kb/065/Q65994/

C: IF NOT EXIST C:\WIN\ GOTO NOWINDIR CD \WIN :NOWINDIR

trailing backslash ('\') seems to be enough to distinguish between directories and ordinary files.
