After further inspection, it is obvious that the downloaded programs are installed without compression.

This means that the total of downloaded material is near 9GB with the limit of 4.4GB in compressed mode.

Examining the listing of files for KNOPPIX DVD 3.5( there are ~2GB of compressed files on the DVD) shows 2660 apps listed.

It seems therefore I must load somewhere in the vicinity of 2600 apps to reach a total exceeding the 2GB limit with room to spare.

For this test, the actual app isn't the important factor but the total size is.
