How to compare two Foreach loops - windows

Question

My current script checks if a specific folder on some clients exists.
I'd like to check if the client is online or offline before checking if the folder exists.
My current script looks like this:
$CDS = Get-content C:\Users\XY\Desktop\Clientliste.txt
Foreach($c in $CDS) {
IF (Test-Connection -BufferSize 32 -Count 1 -ComputerName $c -Quiet) {
Foreach ($c in $CDS) {
$Test = Test-Path -path "\\$c\c$\apps\perl"
Start-Sleep -s 0.25
If ($Test -eq $True) {
Write-Host "Path exists on $c."
}
Else {
Write-Host "Path NOT exist on $c."
}
}
}
Else {
Write-Host "The remote computer " $c " is Offline"
}
}
I don't know how to link the foreach loops so that they work together.
Because when I run my script now, it goes after the first if request in the 2nd foreach loop and it does leave it first, when it finishes the 2nd foreach loop.
I don't want that. I want that if the client is online, it checks if the paths exists and then goes to the next client and checks again if it is online and then...
Maybe you can help me :)

Why do another identical loop over the items from the text file is you have already tested the machine is reachable?
Just remove that second loop and do:
$CDS = Get-Content -Path 'C:\Users\XY\Desktop\Clientliste.txt'
foreach($computer in $CDS) {
if (Test-Connection -BufferSize 32 -Count 1 -ComputerName $computer -Quiet) {
if (Test-Path -Path "\\$computer\C$\apps\perl" -PathType Container) {
Write-Host "Path exists on computer '$computer'."
}
else {
Write-Host "Path NOT exist on computer '$computer'."
}
}
else {
Write-Host "The remote computer '$computer' is Offline"
}
}
