JSFile

Overview

The JSFile is an IScriptObject representation of a file, supporting local, remote, and web contexts. It provides functionalities to manipulate files, such as checking read/write permissions, creating or deleting files, and managing file properties like size, type, and last modified date. Operations on directories are also supported, allowing directory creation and listing of contents.
