Hi everyone, I ve got a strange behavior with bz2 and gzip. When i compress a small folder around 225 Mo the compression goes to 49 Mo for gzip 46 mo for bzip2 When i compress a bigger folder around 5 Go the compression goes to 2.6 Go for gzip 3.1 mo for bzip2 Bzip2 has a better compress for Small folder and gzip has a better one for big folder. Has anyone of you has the same effect. Maybe gzip did'nt compress everything how can i check this. Should i be worried. It's mostly office document. Happy new year, Franck -- Franck
