Given below is the Powershell script that explains how we can get details of all the attachments of a SharePoint List.
$web = Get-SPWeb -Identity http://abhay-pc:9999
$list = $web.Lists["ResourceResume"]
foreach ($item in $list.Items)
{
$attachmentCollection = $item.Attachments
$folder = $web.GetFolder($attachmentCollection.UrlPrefix);
foreach ($file in $folder.Files)
{
Write-Host $item.Title
Write-Host $file.Name
Write-Host $file.Author
Write-Host $file.TimeCreated
}
}
