Zip64Demo
-------------------------------------------------------------------------------------------
Shows how C1Zip supports files larger than 4.3 gigabytes.

The traditional Zip format uses 32-bit unsigned integers in its data structures. This
imposes limits on the maximum number of zip entries, maximum entry size, and maximum
zip file size. The limit is 0xffffffff = 4,294,967,295 (4.3 gigabytes).

To circumvent this limit, the Zip64 format was introduced. This is an extension that
raises the limit from 32 to 64 bits, 18,446,744,073,709,551,615 (18.4 exabytes ;-).

Starting with build 2.1.20102.68, C1Zip supports the Zip64 format.

This sample demonstrates this by performing the following steps:

1 - Create a 4.4 gigabyte file containing random digits
2 - Compress this file into a zip file
3 - Expand the zip file back into another 4.4 gigabyte file
4 - Compare the content of the original file and the expanded one

Warning: This sample deals with very large files and because of that it takes a
         fairly long time to run. The sample does provide user feedback as it
		 progresses.
