I have built a powershell script using the GUI .net framework that provides the user with a graphical interface to add alternate data streams (ADS) to files on a NTFS file system.
Below is the code I wrote for the powershell script:
<#
This script is a GUI featured way to add extended attributes to files

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()
#region begin GUI{

$Form.ClientSize = '600,600'
$Form.text = "Add Extended Attributes"
$Form.TopMost = $false
# Add Extended Attributes Label
$mainLabel = New-Object system.Windows.Forms.Label
$mainLabel.text = "Add Extended Attributes"
$mainLabel.AutoSize = $true
$mainLabel.width = 25
$mainLabel.height = 10
$mainLabel.location = New-Object System.Drawing.Point(180,10)
$mainLabel.Font = 'Microsoft Sans Serif,18'

# label for the file path text box "File Path: "
$FilePathLabel = New-Object system.Windows.Forms.Label
$FilePathLabel.text = "File Path: "
$FilePathLabel.AutoSize = $true
$FilePathLabel.width = 25
$FilePathLabel.height = 10
$FilePathLabel.location = New-Object System.Drawing.Point(80,85)

$description.text = "Description"
$description.AutoSize = $true
$description.width = 104
$description.height = 20
$description.location = New-Object System.Drawing.Point(100,250)
$description.Font = 'Microsoft Sans Serif,10'

[void]$Form.ShowDialog()
Currently the user would have to actually run the powershell script from the root folder and then add the file path to the text input the GUI, along with the rest of the extended attributes. An example of what I currently have is below:
I would like the user to be able to right click on any file and have the form come up with the path of the file that was right clicked in windows explorer, instead of the path being manually entered by the individual making the updates to the alternate data streams. Something similar as how you would extract a file using zip7 (example below).
Can someone tell me if this is even possible? Should I be trying to tackle this problem in another language than using powershell?
You can do all this with Powershell.
First you want to create a script from your code and make input parameter for chosen folder. Like so:
Next you would need to create registry reference for context menu item and powershell script according to it. Like so:
Context menu item:
Chosen directory passed to script's input parameter:
