| Each file is compressed into | | | | | compressor's name on greenish-yellowish background in italics = newly added into the table | | |
| separate archive | | | | | bold black numbers on yellow background = the best result in this column | | |
| | | | | | bold black numbers in italics = the worst result | | |
| | | | | | red numbers (bold in italics)= compressed file is the same or even bigger size than original file (and the worst result) | | |
| Thanks to following people | | | | | gray background = archiver couldn't be run in best mode (mostly due to RAM limiations) | | |
| for their contribution: | | | | | 11KZIP doesn't decompress by itself, 7-zip 4.42 was used for decompression | | | |
| | | | | | 12 QuickLZ compressor family (de)compresses so fast that it is hardware what really limits (de)compression speed. | | | |
