A 'Link Shortcut' is like a quick-access button to a specific program or document on your computer. It's represented by a small icon on your desktop or in your folders (or on your Windows Task Bar):
The little arrow you see on 'Link Shortcut' or '.lnk' icons is there to let you know that it's a shortcut, rather than the actual program or document itself.
This small arrow, found at the bottom left corner of the icon, is like a road sign. It's the computer's way of telling you: "Hey, this icon is a quick path or link to the actual program or document. It's not the main thing itself, but it'll take you there."
This can be quite useful because it helps you distinguish between shortcuts and actual files or programs. It lets you know whether you're opening the real deal or just a handy link that points to it.
You might think of a Link Shortcut like a bookmark for a favorite page in a book.
Now, here's where it gets a little more technical but still pretty simple: a Link Shortcut is actually a special kind of file with the extension '.lnk'. This '.lnk' stands for 'link'. Just like how a '.docx' file might be a Word document, a '.lnk' file is a shortcut link.
When you double-click a '.lnk' file (or shortcut), the computer knows you're not trying to open this '.lnk' file itself. Instead, you're asking to open whatever program or document the '.lnk' file points to. So, if you have a Link Shortcut to Microsoft Word, when you double-click the shortcut, it opens Word.
So, a 'Link Shortcut' or '.lnk' file is a handy way of getting to your programs or documents quickly without having to search for them in your computer's folders.
