Re: file size (or existence) determination in ASP

Hi Conrad:
If you are using vbscript serverside, these should work for you.  Use the
fileSystemObject, which actually has a method "FileExists"  There is also a
script for finding the file size below if you want that as well.


'@  find out if file 'filespec' exists
'@ call by using i.e. ReportFileStatus("C:\images\neat.gif")

Function ReportFileStatus(filespec)
   Dim fso, msg
   Set fso = CreateObject("Scripting.FileSystemObject")
   If (fso.FileExists(filespec)) Then
      msg = filespec & " exists."
   Else
      msg = filespec & " doesn't exist."
   End If
   ReportFileStatus = msg
End Function


'@ this function shows the size of file 'filespec'
Function ShowFolderSize(filespec)
   Dim fso, f, s
   Set fso = CreateObject("Scripting.FileSystemObject")
   Set f = fso.GetFolder(filespec)
   s = UCase(f.Name) & " uses " & f.size & " bytes."
   ShowFolderSize = s
End Function


Hope this helps
