File already exist using system.io.file.copy - asp.net

Question

I'm using System.IO.File.Copy to copy files from serverA to serverB. This works fine accept when the file exsist I get an error "File already exist". I tried trapping it using if file.exsist and nothing.
here is my code.
'Save files to disk
FileUpload1.SaveAs(Server.MapPath("../pdf/audits/" & FileName))
'Local Server
Dim localPath As String = "\\server01\folder1$\pdf\audits\"
'Remote Server
Dim remotePath As String = "\\server02\folder2$\pdf\audits\"
System.IO.File.Copy(localPath + FileName, remotePath + FileName)
What am I missing?

Answer 1

If you just modify your copy operation like this, it should work. The last parameter will overwrite the file.
System.IO.File.Copy(localPath + FileName, remotePath + FileName, True);

Answer 2

If you have large files, you are not going to want to overwrite them everytime. Try fixing your check to see if the file exist. Something like this (C#):
var localPath = #"C:\";
var remotePath = #"\\server\folder\";
var fileName = "test.txt";
if (!new System.IO.FileInfo(remotePath + fileName).Exists)
{
System.IO.File.Copy(localPath + fileName, remotePath + fileName);
}

Answer 3

There's a third parameter to overwrite if it already exists
System.IO.File.Copy(fileName, destName, overwrite);

Answer 4

I got it working with help from RLG.
'Save files to disk
FileUpload1.SaveAs(Server.MapPath("../pdf/audits" & FileName))
'SIGAR Public CMS
Dim localPath As String = "\\hqdadev01\sigar_cms$\pdf\audits\"
'SIGAR Dev
Dim remotePath As String = "\\hqdadev02\sigar_public$\pdf\audits\"
Added this to check.
If Not New System.IO.FileInfo(remotePath + FileName).Exists Then
File.Copy(localPath + FileName, remotePath + FileName, overwrite)
End If
