How does Sony 2500C dump the data in the camera to the memory card?

Hello, I'm glad to answer your question.

If you take a photo without inserting a card, the photo will be stored in the camera's memory. You can use the data cable to import into the computer. After inserting the memory card, there is an option in the settings. You can change the storage destination disk to a memory card, open the file to be moved on your computer, and then copy or cut and paste the file into the memory card.

If there is no data cable, you can insert a memory card (memory stick) into the camera. There is a copy option in the camera menu. Select Copy, and then you can copy the photos in the camera memory to the memory card, and then transfer them to the computer with the card reader.
