Downloaded ZIP file won't open or says it's damaged

Short answer

A ZIP that won't open is usually an incomplete download or a built-in unzip tool that struggles with very large archives. Check the file size, download it again, try a free tool like 7-Zip or The Unarchiver, or download files one at a time.

On a Pandafile download page you can download each file on its own, or everything at once as a single ZIP. The ZIP keeps folders in their original structure. If that ZIP refuses to open, don't worry: the files are fine on our side and there are a few easy fixes.

Download everything as a ZIP, or each file on its own.

1. Make sure the download finished

The most common cause is an incomplete download. Compare the ZIP's size on your computer with the total shown on the download page. If yours is much smaller, the download was interrupted, perhaps by sleep, a dropped connection or a full disk. Free up space, keep the computer awake and download it again.

2. Extract it the right way

  1. Windows: right-click the ZIP and choose Extract All, then pick a folder. Opening it by double-clicking only previews the contents.
  2. Mac: double-click the ZIP and a folder appears next to it.
  3. iPhone or iPad: tap the ZIP in the Files app to unpack it.

Windows uses Extract All; a Mac unzips with a double-click.

3. Very large ZIPs

Built-in tools can struggle with very large archives or ones with thousands of files. If you get an error, try a well-known free tool such as 7-Zip on Windows or The Unarchiver on Mac.

4. Skip the ZIP

You can always download the files one by one from the same page. This is often the easiest option on a phone, or if your ZIP keeps failing.

  • Paths too long on Windows? Extract to a short folder such as C:\Pandafile.
  • Antivirus holding the ZIP? Check its quarantine list.
  • Need more time? The expiry is shown on the download page. Ask the sender to resend before it runs out.
