Powershell to move files to folder in increments and compress each folder

A big thank you to //\O// for his out-zip function! This will do what you want:

function out-zip { 
    Param([string]$path) 

    if (-not $path.EndsWith('.zip')) {$path += '.zip'} 

    if (-not (test-path $path)) { 
      set-content $path ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18)) 
    } 
    $ZipFile = (new-object -com shell.application).NameSpace($path) 
    $input | foreach {$zipfile.CopyHere($_.fullname)} 
}
$Path = "C:\Temp"
$FileList = gci $path
[int]$FilesPerZip=100
For($i=1;$i -le [Math]::Ceiling($FileList.count/$FilesPerZip);$i++){
    md "c:\$($i)"
    gci $path|random -Count $FilesPerZip|%{$_.moveto("c:\$i\$($_.name)")}
}
(1..[Math]::Ceiling($FileList.count/$FilesPerZip))|%{gi "c:\$_"|out-zip "C:\$_.zip"}

Just update your path and how many files you want in each zip file.

This counts how many files in total, divides by how many files you want per zip file, and rounds up. Then it loops through the target directory grabbing X files at random and placing them into sequential numbered folders. Lastly it zips those folders.

It will fail if there are already zip files with the desired name existing already (i.e. C:\1.zip), and will probably throw errors if there are those folders there as well, and will fail if there are those folders AND there are matching files in them, so you will probably want to throw in some checks up front to make sure those folders and files don't exist already, but this answers your Move & Zip question.
