When I run the script below, instead of the values of each object being output to a csv, they are output like the following:

IsReadOnly IsFixedSize IsSynchronized Keys Values SyncRoot Count
FALSE FALSE FALSE System.Collections.Hashtable+KeyCollection System.Collections.Hashtable+ValueCollection System.Object 3
FALSE FALSE FALSE System.Collections.Hashtable+KeyCollection System.Collections.Hashtable+ValueCollection System.Object 3

Anyone know what is going on?

This is the script:

$90 = (get-date).adddays(-90);
$path = (Get-ChildItem "C:\Program Files" -Recurse ) | % { $_.FullName }
$hash = foreach ($p in $path) {
$val = Get-Item -Path $p
if ($val.LastWriteTime -lt $90) {
	lastWrite=$val.LastWriteTime }}}
$hash | Export-Csv C:\scripts\accessed.csv -NoTypeInformation

Wow, that's a convoluted little chunk of code ;). What are you getting if you pipe $hash to Get-Member before exporting it? It's possible the way you're loading $hash is making it so Export-Csv isn't treating it correctly, but can't be sure.

Are you running this on PowerShell v2? That's the only way I can see you'd wind up with a hashtable object instead of a PSObject there.

The [pscustomobject] accelerator requires PSv3 or later. In v2, use the New-Object cmdlet instead.

Dave, yes, I was using version 2 : ( I did finally use the New-Object cmdlet. Thanks both for the help!
