Solution

Follow these steps to create a reusable workflow for clearing the temp folder:

Step 1: Create a New Workflow

1. Create a new Sequence workflow and renamed it as ‘ReusableClearTempFolder.xaml’.

Step 2: Add an "Invoke Code" Activity

1. Drag and drop an Invoke Code activity into your workflow.

2. Set the Language property to VB.Net.

3. Enter the following code snippet:

Dim tempFolderPath As String = Path.GetTempPath()

Try
    Dim tempEntries() As String = Directory.GetFileSystemEntries(tempFolderPath)
    Console.WriteLine("Total temp files : " & tempEntries.Count.ToString)

    For Each entry As String In tempEntries
        Try
            If File.Exists(entry) Then
                File.Delete(entry)
                Console.WriteLine("File deleted: " & entry)
            ElseIf Directory.Exists(entry) Then
                Directory.Delete(entry, True) ' Deleting a folder recursively
                Console.WriteLine("Folder deleted: " & entry)
            End If
        Catch ex As Exception
            Console.WriteLine("Failed to delete: " & entry & " - " & ex.Message)
        End Try
    Next
Catch ex As Exception
    Console.WriteLine("An error occurred: " & ex.Message)
End Try

Explanation of the Code

• Path.GetTempPath(): Retrieves the path of the system's temp folder.

• Directory.GetFileSystemEntries(): Lists all files and subdirectories in the temp folder.

• File.Delete(): Deletes individual files while handling potential exceptions.

• Directory.Delete(entry, True): Deletes directories and their contents recursively.

• Try-Catch: Ensures that errors during deletion are handled gracefully and logged.

  
  

Step 3: Test and Validate

1. Integrate the workflow into your automation process and verify that the unnecessary files and folders are being cleared effectively. For example:
