ForEach-Object to look in subfolders - powershell

Question

I Have this powershell script “copFiles.ps1” that looks in a txt file "Filestocopy.txt" for a list and copies them to a destination
$source = "C:\Data\Filestocopy.txt"
$destination = "C:\Data\Models"
Get-Content $source | ForEach-Object {copy-item $_ $destination}
It’ll only copy the files if they’re in the same folder as the .ps1 file and it ignores subfolders, how can I get it to look in subfolders of the folder that its in, I gather I need to use the -recurse option but don’t know how to rewrite it so it works.
The .ps1 file is fired by a bat file.
Many thanks

I don't know how fast this will be, but you can give an array as the argument for the -Path parameter of Get-ChildItem add the -Recurse switch to dig out the files in subdirectories and simply pipe them along to Copy-Item. something like:
Get-ChildItem (Get-Content $Source) -Recurse |
Copy-Item -Destination $destination
You may also want to add the -File switch.
Update
Based on your comment I played around with this a a little more:
$source = "C:\Data\Filestocopy.txt"
$Destination = "C:\data\Models"
# Get-ChildItem (Get-Content $Source) -Recurse |
Get-ChildItem (Get-Content $Source) -Recurse -File |
ForEach-Object{
If( $_.Directory.FullName -eq $Destination )
{ # Don't work on files already present in the destination
# when the destination is under the current directory...
Continue
}
$FileNum = $null
$NewName = Join-Path -Path $Destination -ChildPath $_.Name
While( (Test-Path $NewName) )
{
++$FileNum
$NewName = Join-Path -Path $Destination -ChildPath ($_.BaseName + "_" + $FileNum + $_.Extension)
}
Copy-Item $_.FullName -Destination $NewName
}
This will increment the destination file name in cases where a file by that name already exists in the destination. If the destination is under the current directory it will prevent analyzing those files by comparing the path of the file to the destination. Files must have unique names in a given folder so I'm not sure how else it can be handled.
