Examples

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

Remarks

To determine which attributes are set, use the And operator to perform a bitwise comparison of the value returned by the GetAttr function and the value of the individual file attribute you want. If the result is not zero, that attribute is set for the named file. For example, the return value of the following And expression is zero if the Archive attribute is not set:

Result = GetAttr(FName) And vbArchive  

A nonzero value is returned if the Archive attribute is set.
