    Just write in a separate file, delete the old and rename the new. Alternatively, read the file into memory, do the manipulation, then write to the file of the name of your choosing.

    I tried that b4 writing to memory but it didnt work for me.. what i want is not to change the file. let say i have this input.txt file i want the changes to occur in that particular file not in output.txt file ( file has to be same) . I have the code for coping one file to another when u make changes but, i want the file name to be same...

    any idea or do you have any example code
