You will have to create a temporary file, copy over the data that you want to keep, and then replace the original file with the temporary. Unless the undesirable data is at the very end of the file, in which case you can simply truncate the existing file. > For example i write few objects into file, and than i want > to delete 5th object from file. Create a new file that contains a copy of items 1 through 4 and 6 through the end of the file. Gambit
