Question

My app Windows forms .NET in Win XP copy files pdfs in shared network folder in a server win 2003.

Admin user in Win2003 detects some corrupt files pdfs, in that shared folder.

HOw can I check if a file is copied right in shared folder ??

the code: I use two ways to copy/move files to shared folder

1. NOte: my app generates PDFs files

2. Write Bytes to disk (the shared folder)

   Public Shared Function GenerarFicheroDeBytes(ByVal datosFichero As Byte(), ByVal rutaFisicaFichero As String) As FileStream

   If Not Directory.Exists(Path.GetDirectoryName(rutaFisicaFichero)) Then
       Directory.CreateDirectory(Path.GetDirectoryName(rutaFisicaFichero))
   End If
   
   Dim fs As New FileStream(rutaFisicaFichero, FileMode.OpenOrCreate, FileAccess.Write)
   fs.Write(datosFichero, 0, datosFichero.Length)
   fs.Flush()
   fs.Close()
   Return fs
   

   End Function

2 Move File to shared network folder

Public Function MoverFicheroABuzonParaIndexar(ByVal rutaProcesarFicherosBuzon As String, ByVal nombreFichero As String) As String

Dim nombreFicheroPDF As String = String.Empty
Dim nombreFicheroPDFRenombrado As String = String.Empty
Dim nombreFicheroBuzon As String = String.Empty 

     nombreFicheroPDF = ... Path.GetFileNameWithoutExtension(...)
     nombreFicheroBuzon = ObtenerRutaFicheroBuzonParaIndexar(...)

      File.Move(nombreFicheroPDF, nombreFicheroBuzon)
Return nombreFicheroBuzon

End Function

To answer the question, unless you know the resulting format of the file – the only entity that can tell you if a file is corrupt or not is the application that attempts to use it. “Corruption” has no context outside of trying to use the file, it’s like saying a .doc is corrupt because my CAD application can’t read it, only Word can.

Also, File.Copy and File.Move exist as shortcut methods for moving files instead of manually streaming them yourself.
