    read file (for example usinf fgetc)
    check char - using isupper, or isalpha or other suitable function
    write char to the new file if it is ok
    delete the old file and rename the new file

    if file is not too big:
    read file (for example usinf fgetc)
    check char - using isupper, or isalpha or other suitable function
    add it to the buffer if condition passed

    when the whole file is processed - overwrite it with the buffer prepared
    To be or not to be == true
