用win7自带的powershell可以轻松修改文档/文件夹创建时间、修改时间。而且可以批量修改。

1. 步骤

新建一个bat文件，在其中添加语句：

@ECHO OFF powershell.exe -command "ls 'folder_path\*.dll' | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }" PAUSE 2. 解释

代码将folder_path路径下的所有dll文件的创建时间和修改时间改成现在的时间。

-command: tells powershell to run the following command and return immediately

ls: list all matching files at the path specified

foreach-object: run the following block on each file that ls found

$_.LastWriteTime = Get-Date: for each file, set the LastWriteTime to the value returned by Get-Date (today’s date and time)

$_.CreationTime = Get-Date： for each file, set the CreationTime to the value returned by Get-Date (today’s date and time) 3. 修改至指定时间

将$_.LastWriteTime = Get-Date:改为$_.LastWriteTime = '01/11/2004 22:13:36'：

@ECHO OFF powershell.exe -command "ls 'folder_path\*.*' | foreach-object { $_.LastWriteTime = '01/11/2004 22:13:36'; $_.CreationTime = '01/11/2004 22:13:36' }" PAUSE 4. 递归文件夹中所有文件 @ECHO OFF powershell.exe -command "Get-Childitem -path 'E:\project_llj\install\test\' -Recurse | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }" PAUSE 参考：
