This module supports the Visual Basic language keywords and run-time library members that access files and folders.
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
