List view or Grid view in Google Drive. Both are helpful! List view shows a text list of your documents. Grid view shows a visual tile of your documents.
There is a toolbar icon to toggle list view and grid view. It is the 4 squares under the G Suite logo in the upper right hand corner.
Clicking on the 4 squares icon will change it to Grid view and the icon will change to an icon that looks like 3 lines with squares next to them to indicate the ability to toggle back to list view.
V for VIEW
