Where Your Downloads Go

It's almost certainly still there — you're just looking in the wrong place. Open your browser's download list (Ctrl + J on Windows/Linux, Command + J on Mac) and it will show you the exact file name and location. If a browser was set to a custom download folder, the file won't be in the default Downloads folder.

Generally, yes. The Downloads folder is just a holding area — deleting files from it doesn't uninstall apps or remove anything from the cloud. Just make sure you've already installed any setup files and moved anything important (like documents or photos) to a permanent location before deleting.

Browsers add a number to the filename if a file with the same name already exists — you'll see things like document.pdf, document (1).pdf, document (2).pdf. This happens when you download the same file multiple times. Keep the most recent one and delete the rest.

In most browsers, go to Settings > Downloads and enable the option that says something like "Ask where to save each file before downloading" or "Always ask you where to save files." This way you can organize files as you download them instead of everything piling up in one folder.

On Windows, yes — right-click the Downloads folder, go to Properties > Location > Move, and pick a folder on the external drive. On Mac, you can change each browser's download location individually to a folder on an external drive, but the system Downloads folder itself stays in your home directory. Just keep in mind that if the drive isn't connected, downloads will fail.
