Set file to 'Writable' with PowerShell

Question

I'm trying to set a few files to writable, but I'm having an issue. I have tried using:

 $file = "path/to/my/file.dat"
 $file = Get-Item $file 
 $file.IsReadOnly = $false

As well as everything listed here:

How to Remove ReadOnly Attribute on File Using PowerShell?

But it still isn't working, at least I don't think it is because when I check the file properties the 'Read-Only' box is still checked:

UPDDATE::

When I run:

$file.isReadOnly

it returns $false, but the box below is explicitly checked? Are these two different things?

I'm wondering what I'm doing wrong, or how to make it so this file is editable.

Answer 1

This works:

Get-Item -Path "path/to/my/file.dat" |
    Set-ItemProperty -Name IsReadOnly -Value $false

Answer 2

You can actually skip the first line:

$file = Get-Item "path/to/my/file.dat"
Set-ItemProperty $file -Name IsReadOnly -Value $false
