如果存在未在批次工作 [英] if exist not working in batch

问题描述

我努力使创建一个简单的文本文件.bat文件。我的问题是Windows XP中的主文件夹 C：\\ Documents和Settings ，而Vista和高于 C：\\ Users \\ <用户/ code>

I am trying to make a .bat file that creates a simple text file. My problem is Windows XP home folder is C:\Documents and Settings while vista and above its C:\Users\

我运行这一点，不管是什么，我把用于路径名，我总是存在

I am running this and no matter what I put for the path name, I always get it exists

@echo off
if exist C:\Documents and Settings\ (
    echo it exists
    Pause
) else (
    echo file not found
    Pause
)

当我运行上面我得到存在的时候，其实它并没有因为我的Windows 7我在做什么错了？

When I run the above I get it exists when in fact it does not since I am windows 7. What am I doing wrong?

推荐答案

首先，你缺少的路径周围的引号。第二个 EXIST 如果只检查存在的文件。有几个秘密的文件时，Windows将使用其文件系统。请尝试以下操作：

Firstly, you are missing quotes around the path. Second EXIST only checks if files exist. There are a few secret files Windows uses in its file system. Try the following:

@echo off
if exist "C:\Documents and Settings\NUL" (
    echo it exists
    Pause
) else (
    echo Folder not found
    Pause
)
