# SOLIDWORKS PDM Professional API Help

# Destroy Deleted Files in Vault Example (C#)

This example shows how to create an application that displays a form in which a user can select the vault in whose root folder and subfolders all deleted files will be permanently destroyed. The user must have permission to delete files.

NOTE: If using the primary interop assembly provided with SOLIDWORKS PDM Professional, see Using .NET Framework 4.0 in Stand-alone Applications.

IMPORTANT: Do not recreate and run this example if you do not want to destroy all deleted files in the root folder and subfolders in the selected vault. Instead, SOLIDWORKS PDM Professional suggests that you review the code to understand how you can programmatically destroy deleted files in the root folder and subfolders of a vault.

//--------------------------------------------------------------------------------------
// Preconditions:
// 1. Start Microsoft Visual Studio.
// 2. Click File > New > Project > Visual C# > Windows Forms Application.
// 3. Type DestroyDeletedItemsCSharp in Name.
// 4. Click the Browse button and browse to the folder where to create
// the project.
// 5. Click OK.
// 6. Replace the code in Form1.cs with this code.
// 7. Replace the code in Form1.Designer.cs with this code.
// 8. Add EPDM.Interop.epdm.dll as a reference (right-click the project
// name in the Solution Explorer, click Add Reference, click Framework
// in the left-side panel, browse to the top folder of your SOLIDWORKS
// PDM Professional installation, locate and click EPDM.Interop.epdm.dll,
// click Open, click Add, and click Close).
// 9. Right-click EPDM.Interop.epdm in References, click Properties, and
// set Embed Interop Types to False to handle methods that pass arrays
// of structures.
// 10. Switch back to the Form1.cs code window.
// 11. Ensure that the namespaces specified in all of the *.cs files match
// the project name.
// 12. Delete one or more checked-in files from the root folder of your vault.
// 13. Click Debug > Start Debugging or press F5.
//
// Postconditions:
// 1. Displays the Destroy Deleted Files dialog.
// 2. Select a vault.
// 3. Optionally select the Include all subfolders check box.
// 4. Click the Destroy deleted files button.
// A message box pops up informing you that:
// * No deleted files were found to destroy.
// - or -
// * The deleted files were destroyed.
// 5. Click OK in the message box.
// 6. Close the Destroy Deleted Files dialog.
