8.9 Program and OS File Compression
Q: What is Gzip?
A: Gzip is the GNU zip archive file format. This file format and the algorithms
used to create it are open source and free to use for any purpose. Files with the .gz
extension have been passed through these data compression algorithms to make
them smaller. For more information, go to www.gnu.org.
Q: Is there a difference between Gzip and zip?
A: While similar, Gzip and zip use different file compression formats and
algorithms. Only program files and OSs compressed with Gzip are compatible
with the CR1000.
Q: Why compress a program or operating system before sending it to a CR1000
datalogger?
