GetAttr Function

Returns a FileAttribute value representing the attributes of a file, directory, or folder.

Public Function GetAttr(ByVal PathName As String) As FileAttribute


Required. String expression that specifies a file, directory, or folder name. PathName may include the directory or folder, and the drive.

Return Values

The value returned by GetAttr is the sum of the following enumeration values:

Value Constant Description
Normal vbNormal Normal.
ReadOnly vbReadOnly Read-only.
Hidden vbHidden Hidden.
System vbSystem System file.
Directory vbDirectory Directory or folder.
Archive vbArchive File has changed since last backup.
Alias vbAlias File has a different name.
Note   These enumerations are specified by the Visual Basic language. The names can be used anywhere in your code in place of the actual values.


Exception type Error number Condition
IOException 52 Pathname is invalid or contains wildcards.
FileNotFoundException 53 Target file does not exist.


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.


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
