參考博文：windows用powershell修改文檔/文件夾創建時間、修改時間
用win10自帶的powershell可以輕松修改文檔/文件夾創建時間、修改時間。而且可以批量修改。
1. 步驟：
新建一個bat文件，在其中添加語句：
@ECHO OFF powershell.exe -command "ls 'folder_path\*.dll' | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date; $_.LastAccessTime = Get-Date;}" PAUSE
2. 解釋：
代碼將folder_path路徑下的所有dll文件的創建時間和修改時間改成現在的時間。
-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)
$_.CreationTime = Get-Date： for each file, set the CreationTime to the value returned by Get-Date (today’s date and time)
3. 修改至指定時間：
將$_.LastWriteTime = Get-Date:改為$_.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. 遞歸文件夾中所有文件：
@ECHO OFF powershell.exe -command "Get-Childitem -path 'E:\project_llj\install\test\' -Recurse | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }" PAUSE
5. 遞增變量設置函數接口：
AddYears、AddMonths、AddDays、AddHours、AddMinutes、AddSeconds、AddMilliseconds、AddTicks
