File System Object

This is an additional library that offers clear, object-orientated access to all the common file and directory functions.

FileSystemObject Object

The FileSystemObject object is the object that actually gives you access to a system's files using 27 methods and only one property.
When creating folders you must create them, one level at a time. You cannot create a folder and a subfolder at the same time.
You should always use the server names instead of the letters as different PC's may have different letters assigned
We won't try to define all of the methods, but we'll review a few as we use them in code examples a little later.
In addition, FileSystemObject is used to return an object that can create, read and edit text files (ASCII and Unicode).
Once you have a new instance of the FileSystemObject, you can work with drives, folders and files, which provide easy access to the file system and simplify the process of reading and writing to a text file.

Dim objFSOFileSystemObject As Scripting.FileSystemObject 
Set objFSOFileSystemObject = New Scripting.FileSystemObject 

Dictionary Object

Dim objFSOFileSystemObject As Scripting.Dictionary 
Set objFSOFileSystemObject = New Scripting.Dictionary 

Important

Unfortunately the FileSystemObject is not suitable for working with binary data. For this you must use the traditional functions.
