When you take a screenshot on your Mac, the file is saved onto the Desktop. If you find yourself having to move the files to some other destination folder manually, you can update your preferences so that screenshots are saved into any folder on your Mac.

To do this you need to open the terminal application and then enter the following commands:

defaults write com.apple.screencapture location /Users/YOUR_USER_NAME/

killall SystemUIServer

in this example, the screenshots would then be saved into the /Users/YOUR_USER_NAME/ folder. Obviously you should update this command to match a folder that actually exists on your computer where you want the screenshots to be saved into.
