将所有文件从所有子文件夹移动到新目的地，并按Powershell中每个组的特定文件数量进行处理

Question

I have the following code to copy all files including those in subfolders from it's root folder to new destination, but I need to separate them into groups and keep the original folder structure.

When i run it, I'll get an error saying that the specified path, file name, or both are too long. It looks like it merges filenames and it's paths together or something like that. I can't figure out how to fix it.

What am I doing wrong?

# Get List Of All Files
$FileList1 = gci $path -recurse

# Remove Last Slash From The Path
$pathnoslash =  $path.Substring(0,$path.Length-1)

# Add Escape Slash To The Path For Regex
$regexpath = $pathnoslash -replace "\\", "\\"

# Move All Files From All Folders
For($i=1;$i -le [Math]::Ceiling(($FileList1.count)/$NumberOfFilesPerFolder);$i++){
    # Get Directory Names
    $newpath = (gci $path -recurse).DirectoryName |

    # Replace Source Root Folder By Destination Root Folder
    ForEach-Object { $_ -replace "$regexpath", "c:\ZIPPINGFOLDER\$i" }

    # Move Files Form Source To Destination
    gci $path -recurse -File | Select-Object -First $NumberOfFilesPerFolder |
    %{$_.moveto("$newpath\$($_.name)")}
}

Answer 1

this worked for me

$NumberOfFilesPerFolder = 2
$newbase = 'c:\temp\zippingfolder'
$path = 'c:\temp\new'
$files = dir $path -Recurse -File
$pathnoslash = $path.TrimEnd('\')
$regexpath = [regex]::Escape($pathnoslash)

$filecount = 0
$foldernum = 0
foreach ($file in $files) {
    if (!($filecount % $NumberOfFilesPerFolder)) {
        $foldernum++
    }
    $filecount++

    $destdir = Join-Path $newbase $foldernum

    if (!(Test-Path $destdir)) {
        $null = md $destdir -Force
    }

    # if the file.txt already exists, rename it to file-1.txt and so on
    $num = 1
    $base = $file.basename
    $ext = $file.extension
    $newname = Join-Path $destdir "$base$ext"
    while (Test-Path $newname) {
        $newname = Join-Path $destdir "$base-$num$ext"
        $num++
    }

    move $file.fullname $newname
}
