FileSystemObject

Today, let’s try the FileSystemObject.

What is FileSystemObject?
The FileSystemObject, or FSO, is an often used component to access the file system. For example, you can create files, read the contents of files, determine whether or not a folder or file exists, iterate through the contents of a folder or directory, or any other number of file system-related tasks.

FileSystemObject can be found in Scrrun.dll. In addition to FileSystemOject, Scrrun.dll includes four other objects available for File I/O and other tasks. These objects include the File object, the TextStreamObject object, the Folder object, and the Drive object. We will concentrate on FileSystemObject.
