That sounds rather long. Could you write a short but complete program
which demonstrates the problem, and post it? I'll have a look then.

I just want to create a large file with size of 80MB
and add a char 1 at the end.
Two method I has been used.
i) seek to the End and write one char
ii) open the file , and append it to the end

both method take nearly 30sec to do so
I want to ask whether they is other method can do this job
using a shorter time ?

Thx
Chris


FileStream fs = new FileStream(filename, FileMode.Open);
fs.SetLength(size);
fs.Close();

fs = new FileStream(filename,
FileMode.Append,FileAccess.Write,FileShare.None,16384 );
byte c =1;
fs.WriteByte(c);
fs.Close();
