i'm waiting for Stuffit 12 result on Maximumcompression but never the less i found this link http://my.smithmicro.com/stuffitcomp...itxformat.html that describes what formats it recompress..
StuffIt 12 includes custom recompressors for these file formats:
JPEG (.jpg, .jpeg)
JPEG lossless (.jls)
JPEG 2000 (.j2k)
Note - recompression is only applied when a j2k file is lossless encoded
TIFF (.tif, .tiff)
PICT (.pict, .pct)
PXM (.pbm, .pgm, .ppm)
Zip (.zip, .cbz)
Microsoft Office 2007 & 2008 documents (.docx, .xlsx, .pptx)
so it supports
1- rle compression of bmp,pbm,pgm,ppm,some tif,some pict,psd, some pdf
2- jp2 arithmetic
3- jls arithmetic
4- mp3 huffman
so i think v13 would increase the formats but which is usefull.. i don't think they'd go to "LZX" as MS may trouble them, nor "RAR".. maybe ISO,bin,nrg or OGG,mp4,mpg,avi..
the problem is that its slow ... very slow for a compression task.. like precomp speed which lose in practicality.. or unless they provide a viewer not just an extractor (2.5mb compressed which is too much..)which let you read/edit/save in sitx format directly.. of images/doc/audio.. so what do you thank plz.?
