code to check file size


helo forum……
How i can check size file. Suppose, if i have some file so if the file greater than 20mb i now wanna archive the file. What the code to check the file size!!!!!!!!!!!!!!!!!!!!!!!!!

hi the code goes like this

Public Function FileSize(ByVal filepath As String) As Long
Dim fi As System.IO.FileInfo = New System.IO.FileInfo(filepath)
Return fi.Length
End Function

but remember this function return will return the size of a file in bytes.
