If you don’t know how to open a certain file type, go to www.openwith.org. There you can search by the extension (.doc, .mp4, .zip, etc.) or by the type of file (video, document, etc.), and the site will tell you which programs will open that file.
To delete multiple files, click the first file…press and hold the Shift key…then click on the last file. All the files from the first to the last clicked will be selected. Then drag to the recyce bin. To select files that are not next to each other, keep the Control keep pressed as you click on the files, and every file you click on will be selected.
