Click on the Trash icon and you’ll be able to see the contents in it.
In case you are new to the macOS world, the Trash app can be found at the right-hand end of the Dock (similar to the Windows taskbar, which is located at the bottom of the display, of course, Dock can be moved to the side). Like Recycle Bin for Windows PCs, Mac computers use Trash to recycle unwanted files you delete. You might have a pretty full trash can or you might be used to emptying it on a regular basis. Once these files are sent to the trash, they are stored in this place until the trash bin is emptied. There are also key commands that will send a file of your choosing to the trash bin in a flash. Mac users will be familiar with the drag and drop into the trash bin features that make it so easy to clean up and remove files. If you have a laptop computer, you also know that storage space is limited, and deleting files can free up precious room for new data and information of whatever variety you need. As easy as it is for our modern machines to allow us to create documents and files, it’s just as easy to get rid of these files in a few simple clicks.
