Vista - need help, powershell

Hi guys,
I need some urgent help to automate a task using powershell. I have tens of thousands of files that need to be re-arranged on daily basis. They structured:

- folder "top"
-----file 1
-----file 2
-----file 3
...
-----sub-folder "2008-10-21"
-----sub-folder "2008-10-22"
-----sub-folder "2008-10-23"
...

I need to
a). check if sub-folder named by today's date (in the format YYYY-MM-DD) exists, if not - create it.
b). move all files from the folder "top" that were *created today* into the new sub-folder.

I know programming a bit but this is too advance for me!
Help is appreciated and karma points are awaiting to be sent.

TIA
Alisa

$rootFolder = "d:\top"
$date = Get-Date
$newDirName = Join-Path $rootFolder ($date -f yyyy-MM-dd)
$null = new-item -path $newDirName -type container -force

dir $rootFolder | where {!$_.PSIsContainer -AND ($_.creationTime.date -eq
$date.date) } | move-item -dest $newDirName

How about this:

param($topfolder = ".")

$today = ([datetime]::now)
$dirname = $today.ToString("yyyy-MM-dd")

function isToday ([datetime]$date)
{
$today.Date -eq $date.Date
}


if (! (Test-Path (Join-Path $topfolder $dirname)) )
{
New-item -type Directory (Join-Path $topfolder $dirname) | Out-Null
}

dir $topfolder -exclude $dirname | Where-Object { isToday($_.creationtime) } | move-Item -Destination (Join-Path $topfolder $dirname)

Hi lizardino,

My codes will create directory if necessary:

$dir = 'd:\top'
$files = dir -path $dir | ?{ !$_.PSIsContainer }
$files | %{ [void] (New-Item -ItemType Directory `
$_.CreationTime.ToString("yyyy-MM-dd") -ErrorAction SilentlyContinue);
$_ }`
| %{ Move-Item $_.PSPath -dest $_.CreationTime.ToString("yyyy-MM-dd") }

It will collect all of files under the top directory. Create the directory
and move the file to the correctly directory one by one.

Best regards,
Tao Ma
