Final answer:
Moving or copying a folder affects all of its contents.
Step-by-step explanation:
The statement is true. Moving or copying a folder does indeed affect all of the contents of the folder. When a folder is moved or copied, all of the files and subfolders within it are also moved or copied along with it.
For example, if you have a folder named 'Documents' with several files and subfolders inside, and you move or copy the 'Documents' folder to a different location, all of the files and subfolders within the 'Documents' folder will also be moved or copied to the new location. This ensures that the folder remains intact and all of its contents are moved or copied together.
