More to think about
- Why are files called files?
- Can files contain other files? Is that what a zip file is?
- Can a file be empty?
- Can a file’s name be the empty string?
- A file is generally the unit of organised data on a storage device. So… is an SMS message on your phone a file? If not, what is it? That is, how else can things like messages be stored?
- How can the same picture of a cat be in
cat.jpg? What’s the difference between them? Which one is “best”?
- If you can make a file smaller by zipping it, why don’t we just zip all files again and again, until they are all… tiny?
- What happens when you delete a file? What does securely deleting a file really mean?
- Are symbolic links (sometimes called “aliases”) files?
- Can you delete the directory that you are currently in?
- Is it possible to accidentally delete all the files on your computer?
- If a filename doesn’t have an extension, how can you find out what kind of file it is? What tools are available to help you? How do they work?
