One way in PowerShell to get a collection of file folders is by using the .NET System.IO.Directory.GetDirectories function. Time is short, and I am familiar with that, so I will use the .NET library in this example script.
Here is one way in which it can be done.
$folders=[System.IO.Directory]::GetDirectories("c:\xxxx")
foreach ($folderName in $folders)
{
...
}
If we wanted to, within the loop we could instantiate a System.IO.DirectoryInfo object to give us more information about the folder.
$folder = New-Object System.IO.DirectoryInfo($folderName)
And then we can access the properties on that class, like the folder's LastWriteTime in order to find out how old it is.
Here is a complete script.
$now = Get-Date
$yesterday = $now.AddDays(-1)
$folders=[System.IO.Directory]::GetDirectories("c:\program files")
foreach ($folderName in $folders)
{
$folder = New-Object System.IO.DirectoryInfo($folderName)
if ($folder.LastWriteTime -lt $yesterday)
{
Write-Host("Folder " + $folderName + " is at least a day old")
}
else
{
Write-Host("Folder " + $folderName + " is less than a day old")
}
}
