# SOLIDWORKS PDM Professional API Help

# Traverse Folders and Files in Vault Example (C#)

This example shows how to recursively traverse all of the folders and files in a vault.

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

//----------------------------------------------------------------------------
// Preconditions:
// 1. Start Microsoft Visual Studio.
// 2. Click File > New > Project > Visual C# > Windows Forms Application.
// 3. Type TraverseFilesFoldersCSharp in Name.
// 4. Click Browse and navigate 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. If using Microsoft Visual Studio 2012 and .NET Framework 4.5, ensure
// that the Prefer 32-bit check box is cleared (right-click the project
// name in the Solution Explorer and click Properties. On the Build tab,
// if Platform target is set to Any CPU, ensure that Prefer 32-bit is cleared.)
// 9. Add EPDM.Interop.epdm.dll as a reference (right-click the project
// name in the Solution Explorer, click Add Reference, click Browse,
// navigate to the top folder of your SOLIDWORKS PDM Professional installation,
// locate and select EPDM.Interop.epdm.dll).
// 10. Right-click EPDM.Interop.epdm in References, click Properties, and set
// Embed Interop Types to False to handle methods that pass arrays of
// structures.
// 11. Ensure that the vault contains one or more checked-out files.
// 12. Click Debug > Start Debugging or press F5.
//
// Postconditions:
// 1. Displays a Traverse Folders and Files dialog.
// 2. Select a vault.
// 3. Click Log in, get client log, get checked-out files in vault.
// 4. Displays a message box with the vault type.
// 5. Click OK.
// 6. Populates Client log and Checked-out files.
// 7. Close the dialog.
