  Good Day 
   
  i am using a AsyncUpload(telerik), i am in a point where i am supposed to save the File to a certain Folder. 
  
  
  First i check if the directory exist 
   
   
  

  Dim baseDire As String = Server.MapPath("~/MyFILES/")

  If IO.Directory.Exists(baseDire & Request("Req_ID").ToString()) = False Then

                 IO.Directory.CreateDirectory(baseDire & Request("Req_ID").ToString())

             End If

  
   
  Because i am doing multiple Upload  , i will have to loop through the items of the Upload control and save to a folder. 
  
  
  

  For Each file As UploadedFile In UploadPropDoc.UploadedFiles

                Dim bytes(file.ContentLength - 1) As Byte

                file.InputStream.Read(bytes, 0, file.ContentLength)

                 'Save the File to the disk

                file.SaveAs(baseDire + file.GetName())

            Next

  
  
  
  Now when ever i debug this , when it comes to this line 
  
  
  

  file.SaveAs(baseDire + file.GetName())

   
  
  
  i get an Error 
   
   The process cannot access the file because it is being used by another process 
   
  
  
  I have removed the Readonly in the Folder that it supposed to write to and gave everyone permission , but still the error persist.
  
  
  Thanks

  Vuyiswa,
  
  Since you did not post your entire code, it's a bit hard to know what is locking the file. But, It looks like you may not be properly creating and releasing the stream that you're feeding to file.InputStream. This process is covered very comprehensively in the IOException when saving forum thread.
  
  If you cannot find the solution in this thread, I'd suggest posting your entire code for review.
  
  Hope this helps!

  hi jumpstart
  
  Thanks , the issue was that i was not closing the Stream. One other thing is that i thought i had to create the file and save it to a certain folder myself , i later looking at the documentation i realised that every postback it post the uploaded files to the "TargetFolder" which is very cool. 
  
  Thanks
