Using WinSCP from PowerShell to retrieve files modified within the last hour - powershell

Question

I'm using a PowerShell script to retrieve a file from a remote directory. I only want to retrieve a file if it was modified within the last hour. I was able to get the most recent file using the following code:
$directoryInfo = $session.ListDirectory($remotePath)
$latest =
$directoryInfo.Files |
Where-Object { -Not $_.IsDirectory } |
Sort-Object LastWriteTime -Descending |
Select-Object -First 1
I believe that I need to add another condition to the Where-Object clause, but I don't know the proper format. For example,
Where-Object { -Not $_.IsDirectory and <created/modified within the last hour> }
How do I do this? Is there a better/simpler way?

Answer 1

Extend you current where-block to check if LastWriteTime is greater (newer) than a datetime-object representing the previous hour. Ex:
$lasthour = (Get-Date).AddHours(-1)
$directoryInfo = $session.ListDirectory($remotePath)
$latest = $directoryInfo.Files |
Where-Object { (-Not $_.IsDirectory) -and ($_.LastWriteTime -gt $lasthour) } |
Sort-Object LastWriteTime -Descending |
Select-Object -First 1

Answer 2

If you want to download all files created/modified within the last hour, use:
$directoryInfo = $session.ListDirectory($remotePath)
$limit = (Get-Date).AddHours(-1)
$recentFiles =
$directoryInfo.Files |
Where-Object { (-Not $_.IsDirectory) -And ($_.LastWriteTime -Gt $limit) }
foreach ($fileInfo in $recentFiles)
{
$sourcePath = [WinSCP.RemotePath]::EscapeFileMask($fileInfo.FullName)
$session.GetFiles($sourcePath, $localPath + "\*").Check()
}
