windows10用powershell修改文档/文件夹创建时间、修改时间、访问时间

参考博文：windows用powershell修改文档/文件夹创建时间、修改时间

用win10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 <span>OFF</span><span>
powershell.exe </span>-<span>command</span><span>"</span><span>ls ‘folder_path*.dll‘ | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date; $_.LastAccessTime = Get-Date;}</span><span>"</span><span>
PAUSE</span>

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 <span>OFF</span><span>
powershell.exe </span>-<span>command</span><span>"</span><span>ls ‘folder_path*.*‘ | foreach-object { $_.LastWriteTime = ‘01/11/2004 22:13:36‘; $_.CreationTime = ‘01/11/2004 22:13:36‘ }</span><span>"</span><span>
PAUSE</span>

4. 递归文件夹中所有文件：

@ECHO <span>OFF</span><span>
powershell.exe </span>-<span>command</span><span>"</span><span>Get-Childitem -path ‘E:project_lljinstall	est‘ -Recurse | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }</span><span>"</span><span> 
PAUSE</span>

5. 递增变量设置函数接口：

AddYears、AddMonths、AddDays、AddHours、AddMinutes、AddSeconds、AddMilliseconds、AddTicks
