使用Powershell查找字符并重命名文件名 [英] Find characters and rename file name using Powershell

问题描述

我在目录中有许多文件使用这种命名约定:"1050_14447_Letter Extension.pdf"，等等.我需要删除第二个下划线(包括第二个下划线)之前的所有字符.因此，新文件名为"Letter Extension.pdf".我该如何迭代单个目录的重命名?

I have a large number of files in a directory with this type of naming convention: "1050_14447_Letter Extension.pdf", etc. I need to remove all characters before the 2nd underscore (including the 2nd underscore). So the new file name would be "Letter Extension.pdf". How can I iterate the single directory renaming accordingly?

推荐答案
