我正在尝试根据文件名将文件复制到特定文件夹。

例如：

当前文件夹 - C:\Stuff\Old Files\

文件- 206.Little Rock.map.pdf

目标文件夹 - D:\Cleanup\206\Repository

所以基本上文件上的前导数字（206）是子文件夹的一部分。“\Repository”将保持不变。只有领先的数字会改变。

如果文件是 207.Little Rock.map.pdf 那么目标文件夹是

D:\清理\207\存储库

我从从这里获得的代码开始，但我不确定如何解释数字的变化以及如果文件夹不存在如何使其创建文件夹。所以 206\Repository 可能已经存在，但如果不存在，我需要脚本来创建文件夹。

$SourceFolder = "C:\Stuff\Old Files\"
$targetFolder = "D:\Cleanup\"
$numFiles = (Get-ChildItem -Path $SourceFolder -Filter *.pdf).Count
$i=0

clear-host;
Write-Host 'This script will copy ' $numFiles ' files from ' $SourceFolder ' to ' $targetFolder
Read-host -prompt 'Press enter to start copying the files'

Get-ChildItem -Path $SourceFolder -Filter *.PDF | %{ 
    [System.IO.FileInfo]$destination = (Join-Path -Path $targetFolder -ChildPath $Name.Repository(".*","\"))

   if(!(Test-Path -Path $destination.Directory )){
    New-item -Path $destination.Directory.FullName -ItemType Directory 
    }
    [int]$percent = $i / $numFiles * 100

    copy-item -Path $_.FullName -Destination $Destination.FullName
    Write-Progress -Activity "Copying ... ($percent %)" -status $_  -PercentComplete $percent -verbose
    $i++
}
Write-Host 'Total number of files read from directory '$SourceFolder ' is ' $numFiles
Write-Host 'Total number of files that was copied to '$targetFolder ' is ' $i
Read-host -prompt "Press enter to complete..."
clear-host;

这应该主要做你需要的。您可能需要稍微调整目标路径，但这应该很容易弄清楚。我强烈建议使用“-”作为文件前缀的分隔符，而不是“。” 因为如果您碰巧在错误的位置执行它，这将防止意外移动目录中的每个文件。

此外，当您编写脚本时，请创建函数来完成各个工作单元，然后在最后调用这些函数。以这种方式修改和调试要容易得多。 

<#
.SYNOPSIS
  Moves files from source to destination based on FileName
  Creates destination folder if it does not exist. 
.DESCIPTION
  The script expects files with a prefix defined by a hyphen '-' i.e. 200-<filename>.<ext>.
  There is no filename validation in this script; it will *probably* skip files without a prefix.
  A folder based on the prefix will be created in the destination. 
  If your file is name string-cheese.txt then it will be moved to $DestinationIn\string\string-cheese.txt
.PARAMETER SourceIn
  Source Path (folder) where your files exist.
.PARAMETER DestinationIn
  Target Path (folder) where you want your files to go.
.EXAMPLE
  & .\CleanUp-Files.ps1 -SourceIn "C:\Users\User\Documents\Files\" -DestinationIn "C:\Users\User\Documents\Backup\" -Verbose

  This script is provided as is, and will probably work as intended.  Good Luck!

这是您可以尝试的方法。目录的编号是从正则表达式匹配中获取的，"(\d+)\..*.pdf". 当您确信将制作正确的文件副本时，请-WhatIf从Copy-Itemcmdlet 中删除 。

我没有尝试解决该Write-Progress功能。此外，这只会复制以数字开头后跟一个句号（句点）字符的 .pdf 文件。

我不完全理解所有Write-Host和Read-Host用法的必要性。它不是很 PowerShell。pwshic

$SourceFolder = 'C:/src/t/copymaps'
$targetFolder = 'C:/src/t/copymaps/base'

$i = 0
$numFiles = (
    Get-ChildItem -File -Path $SourceFolder -Filter "*.pdf" |
        Where-Object -FilterScript { $_.Name -match "(\d+)\..*.pdf" } |
        Measure-Object).Count

clear-host;
Write-Host 'This script will copy ' $numFiles ' files from ' $SourceFolder ' to ' $targetFolder
Read-host -prompt 'Press enter to start copying the files'

Get-ChildItem -File -Path $SourceFolder -Filter "*.pdf" |
    Where-Object -FilterScript { $_.Name -match "(\d+)\..*.pdf" } |
    ForEach-Object {
        $NumberDir = Join-Path -Path $targetFolder -ChildPath $Matches[1]
        $NumberDir = Join-Path -Path $NumberDir -ChildPath 'Repository'
        if (-not (Test-Path $NumberDir)) {
            New-Item -ItemType Directory -Path $NumberDir
        }

        Copy-Item -Path $_.FullName -Destination $NumberDir -Whatif
        $i++
    }

Write-Host 'Total number of files read from directory '$SourceFolder ' is ' $numFiles
Write-Host 'Total number of files that was copied to '$targetFolder ' is ' $i
Read-host -prompt "Press enter to complete..."
