PowerShell: Possible to Determine a File's MIME Type?

Question

Is it possible for PowerShell to determine what a given file's type is? For example, if I pass it a path of C:\Foo.zip, can I have it determine that the file at that path is, in fact, a zip file and not something else?

Answer 1

If you have .NET 4.5+, you can use the static method System.Web.MimeMapping.GetMimeMapping:

> Add-Type -AssemblyName "System.Web"
> [System.Web.MimeMapping]::GetMimeMapping("C:\foo.zip")
application/x-zip-compressed

Credit goes to this answer to a similar question about .NET.

Edit: Misread the question. GetMimeMapping returns the MIME type by extension, it doesn't analyze the contents.
