批处理文件中的第二个进程无法访问第一个进程创建的文件 [英] Second process in batch file can not access file created by first process

问题描述

嗨 

我有两个程序'A'和'B'。

我正在批量执行这两个程序文件顺序。 'A'流程在网络位置创建一个文件并终止，'B'流程读取流程'A'创建的文件。 

但是流程'B尝试打开文件，我发现找不到文件错误。

如果我在进程A执行后在批处理文件中加1秒睡眠，那么B可以读取该文件。我也使用本地文件夹，然后B也可以读取文件。

那么为什么流程'A'创建的文件不能立即用于流程'B'？  Windows OS是否需要一些时间来更新其他进程的文件可见性？

是否在创建文件的计算机上安装了防病毒产品 - 即使是内置的Windows AV？通过社区论坛NNTP服务器1.1.55.0\">

Hi 

I have two program 'A' and 'B'.

I am executing these two program through batch file sequentially. 'A' process create one file at network location and terminate and 'B' process read the file created by process 'A'. 

But while process 'B try to open the file, I am getting file not found error.

If I add 1 sec sleep in batch file after process A execution, then B can read the file. Also I use local folder, then also B can read the file.

So why is the file created by process 'A' is not available for process 'B' immediately?  Is windows OS takes some time to update the file visibility for other process??

Is there an anti virus product installed on the machine where the file is created - even the built in Windows AV?
