Why is the SD card saying that its full but nothing is showing up on the card?

If your SD card is indicating it's full but not displaying any files, it may be due to corrupted data or hidden files. Sometimes, file system errors can cause the card to misreport its storage usage. Additionally, if files were deleted improperly or if there are hidden/system files, they might occupy space without being visible. To resolve this, you can try using a file recovery tool, or formatting the card after backing up any recoverable data.
