WinZip Stops Responding and Crashes


WinZip uses smart algorithms to reduce the size of original large files. It is very useful when you’re looking to cap out several GBs of data in a zip file to upload to the cloud or email it to your friends or colleagues. Things may go wrong with the file compressing, encryption and backup program, WinZip. The program tends to crash while opening, compressing, extracting or emailing the files.

Unblock the File

When you download a compressed/ zipped file from the Internet, Windows blocks it automatically as a security measure. Windows blocks the file to avoid execution of potentially unsafe content stored in the compressed file, for example, Executable Files (.exe) and Batch Files (.bat). If your WinZip crashes while loading or extracting contents of a particular compressed/ zip file, unblock it as follows:

  1. Right-click the file you’re attempting to open/ extract using WinZip.
  2. Select Properties.
  3. Uncheck the box named Unblock.
  4. If the file is read-only, uncheck the Read-only box.
  5. Click Apply, and then OK.

  3. Press ENTER.
