Users have brought to our attention a problem with the new BZIP2-compressed files. It appears that Winzip (versions through 16.0) cannot successfully decompress these files (despite claims to support the format). 7-zip (versions through 9.20) has no such problems, but we are looking into other solutions.We have traced the issue to an incompatibility between the pbzip2 utility which we used to (more efficiently) compress the files, using all available processors on our compute nodes, and Winzip. We are currently recompressing the files with single-threaded bzip2 utilities, but this will take about 10 times as long as the original compression procedure.
