仅复制子文件夹中的最新文件 [英] Copy only the latest file from subfolders
问题描述
我有一个包含1000多个文档文件夹的文件夹;每个doc文件夹都有1个或多个版本的文档（可以是excel，word，html类型）。
如何使用PowerShell仅将子文件夹中的最新版本复制到单个文件夹中，以便我可以执行PowerGREP搜索？
获取文件的初始文件夹后;有没有简单的方法来维护它？
非常感谢任何帮助！
我尝试过：
搜索Google&在Code Project上查看了这个帖子：使用Microsoft Powershell进行文件复制
一位同事找到了这个有用的网站：主题：每个子目录中最近修改过的文件的返回日期| PowerShell.org [ ^ ]
他写了以下解决方案。它不排除文件夹，但会遍历文件夹并复制出最新文件：
＃识别要搜索的文件夹
projectsFolder ='C：\ Users \ widewide \Documents \DELETE\ACE增强'
＃获取被搜索文件夹的子文件夹并找到最近修改过的文件
＃按最后修改日期按降序排序这些文件
＃将它们复制到新文件夹并选择Name，LastWriteTime和FullName属性并编写它们到csv #file
Get-ChildItem -LiteralPath
projectsFolder -Directory -Force | ForEach-Object {
＃获取每个子文件夹下的所有文件，按最后修改日期降序排序，选择第一个（最近修改过的文件）并返回
Get-ChildItem -LiteralPath
I have a folder containing 1000+ document folders; each doc folder has 1 or more versions of the document (can be excel, word, html types).
How can I use PowerShell to copy only out the most current version from the sub-folders into a single folder so that I can perform PowerGREP searches?
After I get the initial folder of files; is there an easy way to maintain it?
Any help is greatly appreciated!
What I have tried:
Searched Google & looked at this thread on Code Project: File copy using Microsoft Powershell
A co-worker found this helpful site: Topic: Return date of most recently modified file in each sub-dir | PowerShell.org[^]
He wrote the following solution. It doesn't exclude folders, but does traverse folders and copy out the most current file:
# Identify the folder you want to search
projectsFolder = 'C:\Users\swidene\Documents\DELETE\ACE Enhancement'
# Get the subfolders of the folder being searched and find the most recently modified file
# Sort those files by last modification date in descending order
#copy them to new folder and select the Name, LastWriteTime, and FullName properties and write them to the csv #file
Get-ChildItem -LiteralPath
projectsFolder -Directory -Force | ForEach-Object {
# Get all files under each subfolder, sorted by the last modification date in descending order, select the first one (the most recently modified file) and return it
Get-ChildItem -LiteralPath
