Q&A for How to Use an SD Memory Card

That obviously depends on the storage size of the pictures. Some high resolution pictures are only 70 KB, some are 5 MB. Assuming you will only use .jpg or .png format, and assuming an average size of 3 MB per picture (which is generous), a 16 GB stick will store at least 5,000 pictures. With smaller file sizes, it can hold 100,000 pictures. The "Pictures" folder on my PC holds more than 20,000 files and is less than 4 GB in size.

Move the slider on the left of the card up towards the pins to unlock it.

Highlight all the pictures you need, then copy and paste them to your desktop.
