Why are the photos in the camera in different formats?

There are generally three formats for pictures in digital cameras, jpg, tiff and RAW (the extensions vary depending on the camera). jpg is the most common and is a compressed picture format. tiff is an uncompressed format with better retention of details and is mostly used for printing. The RAW format is uncompressed and retains the original photo information, and needs to be used with a computer and the camera's specialized image adjustment software for post-adjustment. This is mostly used for professional advertising photography or high-precision photography.

The other two formats you mentioned, RAR and TMP, are easy to understand. RAR is a compressed package format. You may have stored other files in the camera card, while TMP is a temporary file format. This It is usually generated automatically, and may disappear automatically after the official document is generated. Never mind it.

So, your card should not be poisoned. I hope what I said will be helpful to you.
