添加文件夹中的新项目时，如何自动运行 bat 文件？

Question

I have a ps1 file which contains the code and a bat file which when i double click runs the code. The ps1 file renames all files in that folder. Here is the code:

get-childitem -path C:\Users\ASUS\Videos\Downloads\*.mp4 | foreach {rename-item $_ $_.name.replace("_"," ")} 

How can I run the bat file to automatically rename all files that are added to that folder?

I saw @olaf mentioned FileSystemWatcher and, honestly, it one of the better options for what you're trying to do.

Alternatively, you can use Task Scheduler to run at specific times, dates, actions, etc. There's also no need to point to the bat file, it can run ps1 files just as easy without having to have.bat execute the.ps1.

Change your ps1 to the following. It's passing only the items that were created less than 30 minutes ago; can be changed to days, minutes, etc. Then, it's just renaming them(:

Get-ChildItem -Path C:\Users\ASUS\Videos\Downloads\*.mp4 | Where-Object {$_.CreationTime -gt (Get-Date).AddMinutes(-30)}| foreach {rename-item $_.FullName $_.name.replace("_"," ")}
