Syntax

File_ListReset()

File_ListReset() is a command used to reset the internal counter or pointer for the file or directory listing process.

This is typically used before you start listing or accessing files and directories on the SD card or storage device.

File_ListReset()

Why Use?

Initialization: Ensures that the list of files or directories starts from the beginning.
Avoid Overlap: Prevents errors or inconsistencies when you attempt to list files or directories more than once without resetting the internal counter.
