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.

Notes

This command will only work if a file is currently open using File_Open(), File_Append(), or File_OpenAt().
