Hello all,


As you know you can do solid compression
with my Parallel archiver using the same method as
Tar.bz2, first you have to archive your files
and after that you can compress them with Parallel Bzip and we call that 
also solid compression.

But i have thought yesterday on how to implement solid compression as 
you find it in 7Zip and RAR, and i have come to the conclusion that i 
need to add support also for
compressing and archiving directly in an in-memory archive so my Parallel
archiver will support a solid block size up
to 64 GB as in 7Zip , it is not so difficult to
implement it, if the solid block size is not so big
for example <= 64 MB you can directly
archive many files into an in-memory archive and after that compress and 
archive the in-memory archive that is <= 64 MB to the a file archive, 
and if the solid block size is bigger you can compress and archive many 
files
files in a file archive and after that compress
and archive this file archive that contains many files into an the archive.

That's how we can implement solid compression as in 7Zip and RAR,
It is not so difficult and i will soon upgrade
my Parallel archiver to support this kind of solid compression using my 
Parallel Bzip and  my other Parallel LZMA.




Thank you,
Amine Moulay Ramdane.
