powershell check for existence of multiple inputs - powershell

Question

I need to check if files from input exists.
I split multiple inputs for example BWMDL.VML BWMDL.STA etc and write out files that are already in folder
I check if files from input are present in folder or not.
But I'm getting True, even if the file doesnt exists, also the output from test-path is printed twice, with different result.
Set-Variable -Name Files -Value (Read-Host "instert file name")
Set-Variable -Name FromPath -Value ("C:\Users\Desktop\AP\AP\parser\*.VML" , "C:\Users\Desktop\AP\AP\parser\*.STA")
Set-Variable -Name NameOfFiles (Get-ChildItem -Path $FromPath "-Include *.VML, *.STA" -Name)
Write-Host "FILES IN FOLDER:"
$NameOfFiles
Write-host "---------------------"
Write-host "FILES FROM INPUT: "
Splitted
Write-host "---------------------"
Write-host "FILE EXISTS: "
ForEach ($i in Splitted) {
FileToCheck
}
function Splitted {
$Files -Split " "
}
function FileToCheck {
Test-Path $FromPath -Filter $Files -PathType Leaf
}
For example I'm getting like this result

You are over complicating this.
Once you get the names of all files with extension .VML or .STA in an array, you do not have to use Test-Path anymore, since you know the files in array $NameOfFiles actually do exist, otherwise Get-ChildItem would not have listed them.
This means you can get rid of the helper functions you have defined, which BTW should have been written on top of your code, so before calling on them.
Try
$Files = (Read-Host "instert file name(s) separated by space characters" ) -split '\s+'
$FromPath = 'C:\Users\Desktop\AP\AP\parser'
# if you need to recurse through possible subfolders
$NameOfFiles = (Get-ChildItem -Path $FromPath -Include '*.VML', '*.STA' -File -Recurse).Name
# without recursion (so if files are directly in the FromPath):
# $NameOfFiles = (Get-ChildItem -Path $FromPath -File | Where-Object {$_.Extension -match '\.(VML|STA)'}).Name
Write-Host "FILES IN FOLDER:"
$NameOfFiles
Write-host "---------------------"
Write-host "FILES FROM INPUT: "
$Files
Write-host "---------------------"
Write-host "FILE EXISTS: "
foreach ($file in $Files) { ($NameOfFiles -contains $file) }
Output should look like
instert file name(s) separated by space characters: BWMDL.VML BWMDL.STA
FILES IN FOLDER:
BWMDL.STA
BWMDL.VML
---------------------
FILES FROM INPUT:
BWMDL.VML
BWMDL.STA
---------------------
FILE EXISTS:
True
True
