File_Size() | TFT & EPD Graphic Library 2

Syntax

File_Size(pFileName As Global_sFileName), Dword

Parameters

Parameter	Description
pFileName	The name of the file whose size you want to check. It should be a string with a maximum length of 12 characters, including the file extension (e.g., "MyFile.txt").

Overview

Result Dword: The size of the specified file in bytes.

Get the Size of a File

File_Size() is used to get the size of a file, specified by its name, in bytes. This function returns the file size based on the file stored on the SD card.

Example

File_Size("MyFile.txt")

Notes

File Size is returned in bytes.
File Size Calculation: If the file is large, the size might exceed the typical range of smaller integer types, so Dword (32-bit) is used to handle large file sizes.

Limitation:

File_Open(), File_Append(), or File_OpenAt(): Ensure that the file is not currently open when using File_Size().
If the file is open, use File_SizeOpen() instead to get the size of the currently open file.
