File_DiskFull() | TFT & EPD Graphic Library 2

Syntax

File_DiskFull(), Bit

Value	Meaning
0	The disk is not full – there is still available space on the SD card.
1	The disk is full – no more data can be written to the card.

File_DiskFull() is a variable, not a procedure, that you can check at any time to determine if the SD card (or the storage medium) is full.

This can help you monitor the available space while performing file operations.

File_DiskFull()

This variable can be checked at any point during your program’s execution, especially before attempting to write new data to the card.
If File_DiskFull returns 1, you should avoid writing more data to the disk, as it won't be successful until space is freed up (e.g., by deleting files or directories).
