When multiple photos are downloaded together, they can be saved as a ZIP file instead of individual image files. That ZIP file is not a PDF, so Adobe Acrobat will not open it.
To use the photos on Windows:
- Locate the downloaded zipped folder.
- Right-click the ZIP file.
- Select Extract All... and follow the prompts.
- Open the extracted folder and confirm the photos open there.
- Copy or move the extracted photo files to the external drive.
A few important points:
- A zipped folder is a compressed container for multiple files.
- Windows can open and extract ZIP files directly.
- If only one photo is downloaded, it may save as a normal image file instead of a ZIP.
- If the external drive is intended to store a ZIP archive, the ZIP can also be copied directly to that drive without opening it first.
If the photos are stored in iCloud and not fully on the device, use iCloud for Windows to access or import them in Windows. In the Photos app, iCloud Photos appears after installing iCloud for Windows, signing in, and enabling Photos in that app.
