Help with a computer storage problem I have please?

Buy a flash drive. Drag and drop your photos there. A memory stick is a reference to the internal memory of a computer. It is inside the unit. It is not removable storage.
If you are referring to application programs that you want to delete, they can only be uninstalled by going to programs and features in control panel.

You don't delete apps, you uninstall them. If you're using Windows go to Control Panel and select Applications.

This will list all the applications installed on your system. Right click on one and click on Uninstall to uninstall it and delete all the files associated with it. Be careful you only uninstall stuff you aren't using such as demos, or maybe games you don't play anymore.

Next right-click on the trash can and click 'empty trash.' By default, when you delete a file it simply gets moved to the trash can but is not deleted. Once you empty the trash, the files are deleted and the space freed up.

Finally, buying a small external hard drive can help by allowing you to move documents and photos off your laptop's drive and onto the external drive. Just be careful and never disconnect the drive unless you have stopped it (right click on the picture of the drive and select eject or stop - this will allow the OS to close all files so you can safely unplug the drive. Shutting down the laptop does the same thing.
