PowerShell Script:
$webApp = Get-SPWebApplication http://webapp.domain
If ($webApp.AllowedInlineDownloadedMimeTypes -notcontains "application/pdf")
{
Write-Host -ForegroundColor White "Adding Pdf MIME Type..."
$webApp.AllowedInlineDownloadedMimeTypes.Add("application/pdf")
$webApp.Update()
Write-Host -ForegroundColor White "Added and saved."
} Else {
Write-Host -ForegroundColor White "Pdf MIME type is already added."
}
In addition, if you want your PDFs to open in a new window or even in Adobe Reader you'll want to change your local Adobe Reader client settings:
Open Adobe Reader
Select “Edit” –> “Preferences” from the menu system.
Select the option on the left called “Internet”
Either select or de-select the option called “Display PDF in Browser” depending on your preference.
SharePoint Administrators, don't forget your PDF iFilter for searching those PDFs!
