How do I get a file path without extension in PowerShell?

Question

I have an absolute path in a variable in my powershell 2.0 script. I want to strip off the extension but keep the full path and file name. Easiest way to do that?

So if I have C:\Temp\MyFolder\mytextfile.fake.ext.txt in a variable called, say $file

I want to return

C:\Temp\MyFolder\mytextfile.fake.ext

Answer 1

if is a [string] type:

 $file.Substring(0, $file.LastIndexOf('.'))

if is a [system.io.fileinfo] type:

join-path $File.DirectoryName  $file.BaseName

or you can cast it:

join-path ([system.io.fileinfo]$File).DirectoryName  ([system.io.fileinfo]$file).BaseName
