    you mean native transFER mode right?
    Do you save the image or do you just transfer it and display it?
    once the image has been send, the source doesn’t really have anything to do with the image anymore, so I don’t think there is anything you should/could send to the source.
    what source are we talking about? scanner?

    aha ok now I get it;
    hmm…I think DAT_FILESYSTEM MSG_DELETE should do the job, but I am not sure because I have never had anything to do with a digi cam.
    Just check on it: twain spec 1.9 page A-519 has quite a few functions for dealing with files and folders

    I found that my twain doesn’t support the DATA of DAT_FILESYSTEM.
    I need a new version higher than 1.8 but where can I download it?

    what do you actually mean with “MY TWAIN”? if you mean the twain driver for your camera -> look at the website of the company that made your camera if you mean your twain.h file is too old-> check http://www.twain.org
