    Hello:

    When I use this code:

    TW_FILESYSTEM fs;

    memset(fs,0,sizeof(fs));
    strcpy(fs.InputName,”FOLDER”);
    fs.Recursive = 1;

    DSMEntry( &app, &src, DG_CONTROL, DAT_FILESYSTEM, MSG_DELETE, &fs );

    I always get a failure. When I look at the condition code, I get Bad Protocol. Please help! The TWAIN specification says that the Bad Protocol means it isn’t supported, and the twain.h file says its a bad MSG, DAT and DG combination. If it isn’t supported, how come the UI can delete the images?? How can I delete the images??? Am I doing something wrong?
