erase the whole file and create it again

you could open the file in write only mode i.e. "w" mode

for example

void main()
{
FILE *fp;

fp=fopen("c:\\mysoftwr\\trial.txt","w");
}

Added after 2 minutes:

pls note that while writing the filename the double back-slash is necessary

U can acess the file flags such as the date and time and attributes(hidden/readonly/system) from the C functions itself, I think ur purpose is solved
