How to delete documents using PowerShell scripting.

This article will show you how to create a PowerShell Delete Documents Stencil to delete documents in a divider named "Temp Divider". Use at your own risk.

1. From the Workflow Designer app, right click an open area and click Properties. 
2. Select PowerShell Global Functions.
3. Copy and paste the following to create a PowerShell script to delete documents in a divider named "Temp Divider".
4. function DeleteDocs() {
   $Context.File.Documents.Fill()
   $Context.File.Documents | ? { $_.Divider -eq "Temp Divider" } | % { $_.Delete() }
   return "done"
   }
5. Click OK.         
6. To use this PowerShell script in your workflow, create and configure a Custom Action stencil by dragging a Custom Action stencil to the workflow diagram window.                           
7. Open the Custom Action. Edit the description so it is meaningful such as Delete E-Form.
8. Add a PowerShell Scripting Action and name it DeleteDocs and click OK.
9. Place the newly created stencil in your workflow diagram where and when you want to delete documents in the divider named "Temp Divider".  You may need to add a Pause stencil to pause a few minutes just before this stencil to make sure document(s) in the "Temp Divider" aren't in use prior to attempting to delete them.
