Get the Size of the Currently Open File
File_SizeOpen() is used to get the size of the file that is currently open. This function provides the size of the file that has been opened for reading or writing, in bytes.
Example:
File_SizeOpen()
Notes:
• This command will only work if a file is currently open using File_Open(), File_Append(), or File_OpenAt().
• To check the size of a different file, you must first close the currently open file using File_Close(), and then you can call File_Size() to check the size of another file.
