It is easy to go crazy snapping pictures when you can store hundreds of pictures on a camera card. You may snap some winning shots, but more likely than not you have several duds in the mix. Deleting pictures one at a time can be tedious and takes a long time, especially if you are going through hundreds of shots. Fortunately, you can select and delete multiple photos at the same time.
Open the folder that contains the pictures you wish to delete.
Hold down the "Ctrl" key on the keyboard.
Use the mouse to click on the thumbnails or icons of the pictures you want to delete. As long as you continue to hold down the "Ctrl" key, each picture you click on is selected.
Hit the "Delete" key. This deletes all the pictures that you selected.
