What does the path '/../' mean?

Wondering where a path that looks like this '/../' would point to outside a file? I'm guessing it might be something like always specifying the root directory and then the relative parent directory to the file it was written in?

Lets break /../ down piece by piece

The first /indicates the root of the file system This is the top most level of the filesystem

.. means the parent folder However, since we are at the top most level, we cannot go higher, so we are still at the top most folder

adding / at the end indicates a folder. This is never mandatory, unless specifying a subfolder path or file. So we are still at the top most folder on the file system.

So, /../ is no different than typing /
