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

Answer 1

# the path
$file = 'C:\Temp\MyFolder\mytextfile.fake.ext.txt'

# using regular expression
$file -replace '\.[^.\\/]+$'

# or using System.IO.Path (too verbose but useful to know)
Join-Path ([System.IO.Path]::GetDirectoryName($file)) ([System.IO.Path]::GetFileNameWithoutExtension($file))

Answer 2

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

Answer 3

You should use the simple .NET framework method, instead of cobbling together path parts or doing replacements.

Answer 4

Here is the best way I prefer AND other examples:

$FileNamePath
(Get-Item $FileNamePath ).Extension
(Get-Item $FileNamePath ).Basename
(Get-Item $FileNamePath ).Name
(Get-Item $FileNamePath ).DirectoryName
(Get-Item $FileNamePath ).FullName

Answer 5

Regardless of whether $file is string or FileInfo object:

(Get-Item $file).BaseName
