Powershell script to find file age from an array - arrays

Question

I'm working on a powershell script to read file attributes filtered by CreationTime on multiple shares. The scripts works, sporadically. It works great when I use a single path but I get mixed results when I add the folders paths to an array. The most disturbing result is when it successfully find and reads all path and then includes everything under c:windows\system32. Same anomaly when shares are empty.
So what I want to accomplish is:
Read list of Shares
Read each share content filtered by 'CreationTime' and 'Archive' attributes.
Save results to a csv file.
If file not empty, write results to event log.
here is the code
$timer = (Get-Date -Format yyy-MM-dd-HHmm)
$Date=(Get-Date).AddHours(-3)
$FolderList = "C:\Software\Scripts\FolderList.txt"
$Folders = get-content $FolderList
$Filepath = "C:\Software\Scripts"
$filename = "$Filepath\" + $timer + "OldFiles.csv"
foreach ($Folder in $Folders)
{
Get-ChildItem $Folder | Where-Object { $_.CreationTime -lt $Date -and $_.Attributes -band [System.IO.FileAttributes]::Archive} | Select Attributes, CreationTime, Fullname | Export-Csv -Path $filename -NoTypeInformation
}
if ( (get-childitem $filename).length -eq 0 )
{
exit
}
else{
#Write to OpsMgr Log
$Message = get-content $filename
Write-EventLog -LogName "Operations Manager" -Source "Health Service Script" -EventID 402 -EntryType Information -Message "Old files found. $Message"
}

This (untested) script might do what you want:
$Date = (Get-Date).AddHours(-3)
$FolderList = "C:\Software\Scripts\FolderList.txt"
$Folders = Get-Content $FolderList
$Filepath = "C:\Software\Scripts"
$timer = (Get-Date -Format yyyy-MM-dd-HHmm)
$filename = Join-Path $Filepath ("{0}_OldFiles.csv" -f $timer)
$Data = foreach ($Folder in $Folders){
Get-ChildItem $Folder |
Where-Object { $_.CreationTime -lt $Date -and
$_.Attributes -band [System.IO.FileAttributes]::Archive} |
Select Attributes, CreationTime, Fullname
}
if ($Data.Count){
#Write to OpsMgr Log
$Data | Export-Csv -Path $filename -NoTypeInformation
$Message = $Data | ConvertTo-Csv
Write-EventLog -LogName "Operations Manager" -Source "Health Service Script" `
-EventID 402 -EntryType Information `
-Message "Old files found. $Message"
}
