Yes, but it's risky.  It's "write-in-place" mode.

Lets say you have a file with 10 records in it numbered 1 to 10.

You want to delete record number 5 from the file.

Open the file twice as file number 1 and 2. (same file)


Read in record 6 and write it out to record 5 then read
record 7 and write it as 6 and so on through the file.

If a disk cache is loaded you will find this to be rather fast.
