Does Windows save where a file was downloaded from?

Yes, for files saved by most browsers. It's stored in a hidden alternate data stream named Zone.Identifier, attached to the file.

Why does File Properties not show the website?

Properties only shows the security warning (“This file came from another computer”). The address is in the same record but Windows doesn't display it.

Is it safe to read Zone.Identifier?

Yes. Reading it changes nothing. Only clicking Unblock or deleting the stream removes it.

How to see where a file was downloaded from on Windows

Updated 13 October 2026

Short answer

When Chrome, Edge, Firefox or Brave saves a file on Windows, it writes a hidden Zone.Identifier record containing the download address (HostUrl) and the page it came from (ReferrerUrl). You can read it with one PowerShell command, or use an app that reads it for every file and groups downloads by website.

Downloaded From: clicking WhatsApp, Gmail and Google Drive shows the files that came from each

Read it with PowerShell

1
Open PowerShell
Right-click the Start button and choose Terminal (or Windows PowerShell).
2
Run the command
Replace the path with your file's path. Tip: Shift+right-click the file and choose “Copy as path”.
3
Read HostUrl
HostUrl is the address the file was downloaded from. ReferrerUrl is the page you were on when you downloaded it.

Get-Content -Path "C:\Users\you\Downloads\file.pdf" -Stream Zone.Identifier

When there's nothing to show

Files copied from a USB drive, a zip, or another folder usually have no record.
Some apps and older browsers write only the zone, not the address.
If you clicked Unblock in the file's Properties, Windows removed the record.
