How to: Determine if a File is Hidden in Visual Basic

The My.Computer.FileSystem.GetFileInfo Method can be used to get a FileInfo object, which contains information about the specified file, including a FileAttributes enumeration.

To determine if a file is hidden

1. Get a FileInfo object for the file you wish to examine. This example gets a FileInfo object for the file Testfile.txt.

   Dim infoReader As System.IO.FileInfo
   infoReader = My.Computer.FileSystem.GetFileInfo("C:\testfile.txt")
   

2. Get a FileAttributes object from the FileInfo object. This example gets FileAttributes from the FileInfo object.

   Dim attributeReader As System.IO.FileAttributes
   attributeReader = infoReader.Attributes
   

3. Query FileAttributes to determine if the file is hidden. This example determines if the file is hidden and displays a result accordingly.

   If (attributeReader And System.IO.FileAttributes.Hidden) > 0 Then
       MsgBox("File is hidden!")
   Else
       MsgBox("File is not hidden!")
   End If
