Final answer:
To select multiple adjacent files, press the Shift key while clicking on the first and last files of the group you want to select. This action highlights all files in between, allowing efficient bulk selection.
Step-by-step explanation:
When selecting several files that are listed next to each other, you press the Shift key on the keyboard. Holding down the Shift key while clicking on the first and last files in a contiguous list will select both of those files and all files in between. This is a common technique used in file management in various operating systems, such as Windows and MacOS, to efficiently select multiple items that are grouped together.
