I'm looking for a compression tool (lzma, gzip, zip et al) with the following characteristics:
1. high compression ratio 2. multiple files per archive 3. very fast decompression/extraction of single files
One of the best from the compression rate point of view is 7z (well, I know it depends on the type of files you are compressing). It definitely satisfies 2. No idea about 3, but worth trying.
Thanks Mark - the last one I tried was indeed 7z (p7zip in the Linux variation), but it fails miserably on 3. AFAICT, when extracting a single file, it scans the complete archive.
Try compressing with '-ms=off' option for p7zip and test decompression speed again...
Interesting, that was a significant improvement. Almost as good as zip and certainly good enough to make 7za a good candidate. Thanks. -- Per Jessen, Zürich (12.9°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
