There exists some further functions to manipulate files that can be useful.

The remove function removes a file given its filename.

int remove(char *filename);

This function returns 0 if success; otherwise, it returns a nonzero value.

The rename function changes the name of the file identified by oldname to newname. We have the possibility to move the file to another directory if we set a path into the newname, not just a filename:

int rename(const char *oldname, const char *newname);

This function returns 0 if success; otherwise, it returns a nonzero value. If it fails for any reason, the original file is unaffected.
