Download and open a file · Build Your Card App

By the endYou can download a file from a web page, find it in your Downloads folder, open it, and read the safety warnings Windows shows.

To download means to copy a file from the internet onto your PC. You will download the Claude app and more. Every download lands in the same place: the Downloads folder.

Where downloads go

In File Explorer, Downloads is in the sidebar.
In Edge, a button with a down arrow appears at the top-right while something downloads, and stays there afterwards. Click it to see the list. Press Ctrl + J to open the full list. The small folder icon next to a file shows it in File Explorer. (Chrome has a similar down-arrow button at the top-right.)

Practice: save a picture

A picture is the safest thing to download. It cannot run or change anything.

In Edge, go to support.microsoft.com, type Snipping Tool in the search box on that page, and open the article called Use Snipping Tool to capture screenshots. It has pictures on it.
Right-click any picture on the page. A menu appears.
Click Save image as. A box opens, already pointing at Downloads. Click Save.
Open File Explorer and click Downloads. The picture is there, a file whose name ends in .png or .jpg (you may not see the ending; step 6 showed how to show it).
Double-click it. It opens in Photos, the PC's picture viewer.
Close Photos with the X, then click the picture once in File Explorer and press Delete. The practice is over.

Kinds of files you will meet

.png, .jpg and .pdf: pictures and documents. Double-click to view. PDFs open in Edge.
.zip: a packed bundle. Right-click it and click Extract All…, then Extract. A folder with the same name appears next to it, unpacked. You can then delete the .zip.
.exe and .msi: an installer or a program. This is how most Windows apps arrive. Double-click it, then click through its pages. Only ever open one you got from the official page this guide pointed you to.

The warnings, and what they mean

Windows and Edge put safety gates in front of downloaded programs. You will meet three. None is an error.

Edge: "isn't commonly downloaded" or "was blocked". Edge is unsure about a file it rarely sees. If the file came from the official page this guide linked to, rest the pointer on that line in the downloads list, click the three dots next to it, then Keep, then Show more, then Keep anyway. If it came from anywhere else, click Delete.
Windows: a blue box saying "Windows protected your PC". This is SmartScreen, the same kind of check at the moment you open the file. For an official download, click More info, then Run anyway. If the box names a publisher you did not expect, stop and close it.
"Do you want to allow this app to make changes to your device?" This is Windows asking before an installer may change the PC. Check that the app name is the one you downloaded, then click Yes. On some PCs it asks for the PIN or password of the person who set the PC up.

If something goes wrong

I cannot find the download. In Edge, press Ctrl + J and click the folder icon next to the file. Or open File Explorer, click Downloads, then click Sort at the top and choose Date modified, so the newest file is first.

The file opened in the wrong app. Right-click the file, point at Open with, and pick the app you want.

Edge asks "Open" or "Save". Click Save (or Keep). The file lands in Downloads like any other.

Right-clicking the .zip shows no Extract All. Click Show more options at the bottom of the menu. Or double-click the .zip, click Extract all at the top of the window, then Extract.

Windows says "This app can't run on your PC". You downloaded the wrong version, for example one made for a different kind of chip. Go back to the official page and pick the other download. Step 9 of Part 2 says which one is yours.
