Example

This example uses the GetAttr function to determine the attributes of a file and directory or folder.

Dim MyAttr As FileAttribute
' Assume file TESTFILE is normal and readonly.
MyAttr = GetAttr("C:\TESTFILE.txt")   ' Returns vbNormal.

' Test for normal.
If (MyAttr And FileAttribute.Normal) = FileAttribute.Normal Then
   MsgBox("This file is normal.")
End If

' Test for normal and readonly.
Dim normalReadonly As FileAttribute
normalReadonly = FileAttribute.Normal Or FileAttribute.ReadOnly
If (MyAttr And normalReadonly) = normalReadonly Then
   MsgBox("This file is normal and readonly.")
End If

' Assume MYDIR is a directory or folder.
MyAttr = GetAttr("C:\MYDIR")
If (MyAttr And FileAttribute.Directory) = FileAttribute.Directory Then
   MsgBox("MYDIR is a directory")
End If
