        New version of 7-Zip File Manager will contain two new functions: Split and Combine.
        It will split to .001 .002 ...

      You can use HDCleaner freeware without adaware.

      freaking awesome!

      the only thing missing from this great program

      Does this mean, that an archive must be splitted manually with the "Split" function after compressing and the pieces have to combined before extracting?

      Is the "Split" function a part of 7za.dll?

        Extracting can be done in one step, but if you have all files in one directory.
        Nearest version will have no split in 7za.dll.

          Thanks. What's about multivolume sfx?

            1) .7z multivolume can work, but I still don't like some things in implementation (it requires changings to .7z format), so I'll keep it disabled some time.
            2) .split multivolume now works.

            sfx now doesn't support .split multivolume.
            So there are 2 ways: to develop .7z moltivolume or to develop .split multivolume.
            .7z moltivolume now can have one advantage over .split: CRC for each volume. But for split we can create additional .txt file with CRCs.

      Oh... It's so pity that such a GREAT program can not simple split during archivation...

      Why the .7z format was developed without multivolume support?

        Multivolume is not so simple task.
        You can imagine it so: .7z without multivolume is 2-demension world. And .7z with multivolume will be 3-demension world.

        Splitting during compressiong can be implemented later.

      OK! Thanx anyway! Because it's FREE!

      is it possible to access the split.dll from command line using the -m option?

      that could allow 1 file splitting during compression
      Isay so because I have split one archive  and then joined the pices with

      copy /b arch.7z.000 +  arch.7z.001  arch.7z

      and succeded in extracting the files.

      by the way I think that a different naming scheme could be better: for instance

      arch.v001.7z

      just to avoid registering lots of  file extensions if in future releases 7z will have independent volumes
      (you need only the volumes where the files to extract are stored)

      Thnaks in advance.

        Splitting feature is still under development.
        Now you can use such command:
        7z x b.7z.001
        that will make 2 steps in one command.
        Extracting of 1 step (.7z.001 to -> .7z) will be implemented later with some switch.

        .001.7z extension will be used only if I will use .7z splitting format. Now I use simple splitting, so imho .001 is good extesion for it. And Total Commander also supports it.
