Loop stops prematurely - powershell

Question

I am writing an application that looks through a directory tree and reports if a folder is inactive based on last write time and read only attribute.
However my loop stops after like 7 iterations even though there are thousands of folders.
My code looks like:
function FolderInactive{
Param([string]$Path)
$date = (Get-Date).AddDays(-365)
$anyReadOnly = $false
Get-ChildItem $Path -File -ErrorAction SilentlyContinue | ForEach-Object {
if($_.LastWriteTime -ge $date){
$false
continue
}
if($_.IsReadOnly -eq $false){
$anyReadOnly = $true
}
}
$anyReadOnly
}
Get-ChildItem "some drive" -Recurse | where {$_.PSIsContainer} | Foreach-Object {
Write-Host $_.FullName
FolderInactive($_.FullName)
}
If I comment out the FolderInactive function call in the Foreach loop it prints all the folders, but with the function call it stops after a few iterations. What is happening?

Answer 1

You cannot use continue with the Foreach-Object cmdlet. Foreach-Object is a cmdlet, not a loop. You instead want to use the loop:
function FolderInactive{
Param([string]$Path)
$date = (Get-Date).AddDays(-365)
$anyReadOnly = $false
$items = Get-ChildItem $Path -File -ErrorAction SilentlyContinue
foreach($item in $items)
{
if($item.LastWriteTime -ge $date){
$false
continue
}
if($item.IsReadOnly -eq $false){
$anyReadOnly = $true
}
}
$anyReadOnly
}
This also can be simplified:
function FolderInactive
{
Param([string]$Path)
$date = (Get-Date).AddYears(-1)
$null -ne (Get-ChildItem $Path -File -ErrorAction SilentlyContinue |
Where {$_.LastWriteTime -ge $date -and $_.IsReadOnly})
}
