<h3>Answer1:</h3>

Make sure you get the file extensions right if they have any.

Get-ChildItem -Path C:\folder1\data -Include * -Exclude text.1, folder1 -Recurse | foreach { $_.Delete()}

<em>Edit to answer the comment:</em>

So you want to delete all files and folders in C:\folder1 except of files text.1 and folder.1 in data, other and alpha? It means you cannot remove these 3 folders too so they have to be excluded.

Get-ChildItem -Path C:\folder1\ -Include * -Exclude text.1, folder.1, alpha, data, other -Recurse | foreach { $_.FullName}
<h3>Answer2:</h3>

try this (and dont stay into your dir when you try) :

Get-ChildItem "C:\folder1\data\*" -Recurse | where Name -notin ('text.1', 'folder.1') | Remove-Item -Force -Recurse
