*Sigh* Okay...what about replacing files in a UdfDataburner? There are "Add" methods, but Add will fail if the file exists. So I'd look for a remove...which is only located in the Files property. Fine for me, but how do I determine the index of the file to remove? Should I iterate over all existing files to find the index every time I want to replace a file? Seems horribly inefficient to me? |

Need to check the code as we've dramatically re-worked UDF engine and completely replaced ISO with a new code. Tons of things were changed / added. |

No news on how to replace files yet? |

- Remove - Add We definitely can write a wrapper over these calls called - Replace but it's not there yet. |

Yes, but how to remove and add efficiently? |

You should have some kind of a tree control in your app (if you allow your user to select/add/remove files). Keep reference pointer to file object you add and use it to remove. We'll overwrap the call with one call but it's not going to be faster b/c it's going to perform the same sequence of actions. |

I thought I can help you Sir, as like you I am an user of StarBurnX, hence I am posting my opinion on your question. I think as you are adding files in a folder. So you have parentFolder as DataFolder and it's path with you. Next thing you need is filename, so what you can do is before adding each file you can query for filename in parentFolder like, ' Search the file object fileToDelete = parentFolder.GetFileObject(pathToSearch) It's your choice whether to delete existing file and add new one now. Do what you want here... And if you have deleted the file then add new file. Am I clear, Sir? Thank you. |

Hello, The DataFolder object provides the property Files which gives access to collection of child items ( files and folders). This collection provides the method Clear!! This collection provides also the method Remove, the type of input parameter is Variant so ... the passed value can be Index or File object. P.s. Look into the our examples DataBurner and UDFDataBurner  Regards, Dmitry |

Nope, StarBurnX only exposes a single Remove method, only accepting an int. |

Hmmm ... [ void Remove(object Index) - Member of RocketDivision.StarBurnX.IDataFiles] ... as you see the the Index parameter has type Object!! )Regards, Dmitry |

Ah, I see, thanks. Guess I focused too much on the parameter name. Will try it. |
