PowerShell – Create a Directory (Path/Folder) If It Doesn’t Exit

Frequently in PowerShell, we need to add a directory if it doesn’t already exist.

Generate a Schema from an XML File in PowerShell

While BizTalk includes an XML to XSD schema utility, we can do the same thing in C# or PowerShell (version 5.1 used in this example, but most of the work is done by .Net classes).

And there are PowerShell commands to show you the top files on the disk. But typically, some of the largest files are the paging […]

BizTalk Receive Location Duplicator in PowerShell

How do you create an identical copy of a BizTalk ReceiveLocation within a Receive Port? Well, it cannot be 100% identical. The name will of course have to change, the URI will have to be unique as well. I recently had a case where we wanted the same orchestration to run on two different databases […]
