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：
|
0 1 2 3 |
@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'：
|
0 1 2 |
@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
|
0 1 2 |
@ECHO OFF powershell.exe -command "Get-Childitem -path 'E:\project_llj\install\test\' -Recurse | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }" PAUSE |
