ForEach-Object/Copy-Item only content (not the folder itself!)

Question

I have code that looks for folders and afterwards it looks for the criteria I am telling it. So far so good. Then I got a ForEach-Object with a Copy-Item $_.Fullname in it. The code itself is working and spitting no errors, but I don't want to copy the folder itself + its content. I just want to copy the content of the folder. I already tried things like $_.Fullname/* and so on.

Here's how my code looks like:

Get-ChildItem -Path $DestinationBackup | Where {
    $_.Name -like "$BackupName_Differential3*"
} | ForEach-Object {
    Copy-Item -Path $_.FullName -Recurse -Destination $Differential_Destination -Force
}

Edit 1:

My Folder structure looks like this:

M143                       ← (Root Folder)
├─Backups                  ← (Folder, here are Backups stored)
│ ├─Fullbackup...
│ ├─Incrementalbackup...   ← Copy Content of this folder, without folder)
│ └─Differentialbackup...  ← (Into this folder)
└─Backup_Script.ps1

This ...

Copy-Item -Path $_.FullName -Recurse

... is your issue. The below should be what you wanted.

(Get-ChildItem -Path E:\BackUps -Recurse).FullName

Results before Copy

E:\BackUps\Differential
E:\BackUps\Full
E:\BackUps\Incremental
E:\BackUps\Incremental\IncBU001.bkp
E:\BackUps\Incremental\IncBU002.bkp
E:\BackUps\Incremental\IncBU003.bkp

Copy-Item -Path 'E:\BackUps\Incremental\*' -Destination 'E:\BackUps\Differential'

(Get-ChildItem -Path E:\BackUps -Recurse).FullName

Results after copy

E:\BackUps\Differential
E:\BackUps\Full
E:\BackUps\Incremental
E:\BackUps\Differential\IncBU001.bkp
E:\BackUps\Differential\IncBU002.bkp
E:\BackUps\Differential\IncBU003.bkp
E:\BackUps\Incremental\IncBU001.bkp
E:\BackUps\Incremental\IncBU002.bkp
E:\BackUps\Incremental\IncBU003.bkp
