DefinitionThe current directory (カレントディレクトリ) is the directory a user or program is working from right now, and it changes when you move to another directory.
ExplanationWriting the route from the current directory to the target is called a relative path (相対パス). In most systems, "." stands for the directory you are in and ".." for its parent, one level up. Even for the same file, the relative path may have to be written differently once the current directory changes.
AnalogyDirections such as "go back two corners from here, then turn right" only make sense from where the speaker is standing.
Memory hook"Current" means "present", as in current events: the news that is happening now.
