Hello,
Here is a snippet of how to do so, all you need to do is add this 'Extensibility' business rule to a Data Management Step or launch it directly and you're set:
Dim folderPath As String = "Applications\<Your Application Name>\Batch" ' You can use si.AppName
Dim mylistofFolders As List(Of XFFolderEx)= BRApi.FileSystem.GetFoldersInFolder(si, FileSystemLocation.FileShare, folderPath, True, True)
For Each folder As XFFolderEx In mylistofFolders
If folder.XFFolder.Name <> "Harvest"
Dim configSettings As AppServerConfigSettings = AppServerConfig.GetSettings(si)
Dim sourceFolderPath As String = FileShareFolderHelper.GetBatchFolderForApp(si, True, configSettings.FileShareRootFolder, si.AppName) & "\" & folder.XFFolder.Name
Directory.Delete(sourceFolderPath, True)
End If
Next folder
