How to change files and folders attributes using PowerShell?

PowerShellMicrosoft TechnologiesSoftware & Coding

There are multiple files and folders attribute supported by the Windows Operating System. To check which attributes that files and folders support use DOS command attrib /?

You can see the attributes listed like Read-Only, Archive, etc. You can set the attribute using PowerShell.

For example, we have a file called TestFile.txt and its attribute is ReadOnly and we need to change it to the Archive.

PS C:\> (Get-ChildItem C:\Temp\TestFile.txt).Attributes

Change Attribute code −

$file = Get-ChildItem C:\Temp\TestFile.txt
$file.Attributes = 'Archive'

So we have set the attribute to the ‘Archive’ from ‘ReadOnly’ and when you check it, the attribute should be changed.

PS C:\> (Get-ChildItem C:\Temp\TestFile.txt).Attributes

To set the multiple attributes, you can separate the values by a comma. For example,

$file = Get-ChildItem C:\Temp\TestFile.txt
$file.Attributes = 'Archive','ReadOnly'
(Get-ChildItem C:\Temp\TestFile.txt).Attributes
ReadOnly, Archive

Similar way you can change the attributes of the folder. For example,

$folder = Get-Item C:\Temp
$folder.Attributes = 'Directory','Hidden'

We will check the folder attributes now. This folder is hidden so we need to use -Hidden parameter.

PS C:\> (Get-ChildItem C:\Temp\ -Hidden).Attributes
Hidden, Directory

To change attributes on the multiple files in the same folder, you need to use foreach loop. For example,

Get-ChildItem C:\Test1\ -Recurse | foreach{$_.Attributes = 'Hidden'}

When we check their values, they should be hidden.

PS C:\> Get-ChildItem C:\Test1 -Recurse -Force

Directory: C:\Test1

Mode      LastWriteTime     Length Name
----      -------------     ------ ----
---h--    8/28/2020 7:27 AM 11 File1.txt
---h--    8/28/2020 7:49 AM 11 File2.txt

-Recurse parameter is to retrieve the data from subfolders. If you need only parent folder data attribute change then remove -Recure parameter.
