Download Digits:

The digits are compressed into multiple .ycd files with 1,000,000,000 digits per file.

File # 00 contains digits 1 - 1,000,000,000
File # 01 contains digits 1,000,000,001 - 2,000,000,000
File # 02 contains digits 2,000,000,001 - 3,000,000,000
etc...

To view a small subset of digits, just download the file(s) that contain them.

To view the digits, use the new digit viewer. (download link below)

If you download multiple .ycd files, keep them in the same folder and open any one of them with digit viewer.
The digit viewer will let you access any digit that you have. And if you have all the .ycd files, you can access any digit.
