Error: 'Windows cannot open the folder'

When you try to open the downloaded folder on Windows you see this:

A screenshot of this Windows error. The Compressed (zipped) folder 'C:\Users\<you>\Downloads\Johnny.Decimal LAS.zip' is invalid.
Figure 62.36A. 'C:\Users\<you>\Downloads\Johnny.Decimal LAS.zip' is invalid.

Cause

The file you downloaded from this site contains emoji. Windows isn't very good at handling zip files that contain emoji.

Solution

Option 1: Turn off emoji1

  1. Go to Settings and then the system settings you want.
  2. Change Use emoji? to No.
  3. Go to Downloads and download your system again.

Option 2: Use 7-Zip

If you want to use emoji you can use 7-Zip to unzip the file. This is advanced-level Windows and is left as an exercise for the reader.
