FileSystem Module (Visual Basic) 

The FileSystem module contains the procedures used to perform file, directory or folder, and system operations.

The My feature gives you greater productivity and performance in file I/O operations than using the FileSystem module. For more information, see My.Computer.FileSystem Object.

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
