使用 PowerShell 脚本根据 txt 文件中的文件/文件夹结构移动所有位于一个文件夹中的文件

Question

What I'm trying to achieve is following:

I have a few thousand files in one "Global" folder . Example:

PS D:\Backup\Global> dir

    Directory: D:\Backup\Global

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
------        19.8.2016.     08:25         282208 CBR.docx
------        17.9.2018.     13:37         254803 CMZ.docx
------         6.6.2017.     07:46         191928 Ginekologija.docx
------        6.12.2019.     08:16         192412 HES.docx
------        19.2.2021.     11:56         192925 Hitna medicinska pomoć.docx
*
*
*

And I need to move them to folders/subfolders (that don't exist yet) according to Structure.txt file.

Content of Structure.txt :

D:\Backup\Structured\1 Word files\1 Планови 2018\Prijedlog godišnjeg plana obuke\CBR.docx
D:\Backup\Structured\1 Word files\1 Планови 2018\Prijedlog godišnjeg plana obuke\CMZ.docx
D:\Backup\Structured\1 Word files\1 Планови 2018\Prijedlog godišnjeg plana obuke\Ginekologija.docx
D:\Backup\Structured\1 Word files\1 Планови 2018\Prijedlog godišnjeg plana obuke\HES.docx
D:\Backup\Structured\1 Word files\1 Планови 2018\Prijedlog godišnjeg plana obuke\Hitna medicinska pomoć.docx
*
*
*

Below are the actions that I suppose I need to perform:

1. Read the Structure.txt file
2. For every line in txt check if folders/subfolders exist, create when it doesn't
3. Move file from "Global" folder to folder referenced in "Structure.txt"

I have found a similar script but something is not working in my case...

$des = "$ENV:D:\Backup\Structured"
$safe = Get-Content "$ENV:D:\Backup\Global\Structure.txt" 
$safe | ForEach-Object {
    #find drive-delimeter
    $first = $_.IndexOf(":\");
    if ($first -eq 1) {
        #stripe it
        $newdes = Join-Path -Path $des -ChildPath @($_.Substring(0, 1) + $_.Substring(2))[0]
    }
    else {
        $newdes = Join-Path -Path $des -ChildPath $_
    }
    $folder = Split-Path -Path $newdes -Parent
    $err = 0
    #check if folder exists"
    $void = Get-Item $folder -ErrorVariable err  -ErrorAction SilentlyContinue
    if ($err.Count -ne 0) {
        #create when it doesn't
        $void = New-Item -Path $folder -ItemType Directory -Force -Verbose
    }
    $void = Move-Item -Path $_ -destination $newdes -Force
}

How can I achieve this using powershell script?

Appreciate help on this. Thanks in advance.

Assuming your structure,txt file may contain different paths for the destinations, you could do below to move the files:

$sourceFolder = 'D:\Backup\Global'

# read the structure.txt file and loop through the entries
Get-Content -Path 'D:\Test\structure.txt' -Encoding utf8 | ForEach-Object {
    # create the full file path and name to be found in the source folder
    $file = Join-Path -Path $sourceFolder -ChildPath ([System.IO.Path]::GetFileName($_))
    if (Test-Path -Path $file -PathType Leaf) {
        # file found; split the path from the filename as found in structure.txt
        $targetFolder = [System.IO.Path]::GetDirectoryName($_)
        # create the path if it did not already exist
        $null = New-Item -Path $targetFolder -ItemType Directory -Force
        # move the file
        Move-Item -Path $file -Destination $targetFolder
    }
}
