'Declaration
Function GetFileSize() As System.Long
System.long GetFileSize()
Return Value
the total size of the file.
Remarks
Implementing GetFileSize() for asynchronously loaded font files may require downloading the complete file contents. Therefore, this method should be used only for operations that either require a complete font file to be loaded (for example, copying a font file) or that need to make decisions based on the value of the file size (for example, validation against a persisted file size).
