Abstract:	.gz files cannot be uncompressed using ZIPFileService
Submitted By:	LANSA Technical Support

.gz files are not supported by the ZIPFileService.

LANSA Integrator uses the Java supplied Zip classes which are based on the InfoZip format http://www.info-zip.org

A .gz file uses a different compressed file format. The extension .gz stands for GNU Zip.

GNU Zip or .gz uses a free GNU software implementation of a compression algorithm.

Hence the compression algorithms used by GNU Zip .gz are different from those used in Zip files and so you need different software to open .gz files. http://www.tech-pro.net/howto-open-gz-file.html
