    I think 7z is the best compression method, Also the program is somewhat faster than other programs zip/rar in loading, beside if you use 7zip or bzip2 you will need more system resources to get a better compression and extraction.

    Sadly 7zip can't do iso or bin, but winrar can :(

    7-zip is the fastest compression tool I have come across. Ironically, it does a better job with Zip rather than the native 7z format. :lol: Also it is one of the two native 64bit compression tools available (AFAIK); the other one being Squeez. But Squeez is nowhere near 7-zip's speed. I wish they made it more user friendly and easy to use as WinRAR. 64bit helps to improve 7-zip's performance up to 80%. Even in 32bit mode, it is still faster than WinRAR's compress/decompress performance.

    One problem is that 7-zip has trouble extracting split RAR files that I download most of the times via torrents, using the context menu entry (it doesn't show up :(). So I have to keep WinRAR for those. :(

    7-zip can open/extract ISO, but not BIN. I'm using 4.52 Beta x64

    But I never extract ISO or BIN files. I only mount them Alcohol. :)
    If I need to EDIT them, I use MagicISO Maker.

    Ooops! :shocked:
    7zip actually did open iso, I couldn't test bin coz I don't have one of those files around. I'll be careful about what I say now on :lol:

    I'd also like to keep a single archiver for all archives, it's a pain to use winzip and winrar together and occasionally you will find 7z archives. 7zip can handle zip and 7z and I've had no problems extracting rar archives with it.
    winrar can open 7z, so looks like winzip can be dumped.

    I think it's a problem with the dictionary size used to create a 7z archive.
    If the dictionary size is higher better compression but needs more resources. Small dictionary sizes mean less compression but lesser memory usage.

    As per the 7zip manual
    Dictionary size:
    Specifies Dictionary size for compression method.
    Usually higher Dictionary size gives more compression ratio. But compressing can be slower and it can require more memory.

    Memory (RAM) usage for LZMA compressing is about 11 times more than dictionary size. Memory usage for LZMA decompressing is close to value of dictionary size. Memory usage for PPMd compressing and decompressing is almost equal to dictionary size.

    The problem is not with single RAR files. See this pic. I can't extract the split RAR archive with right click menu. If it was there, there is not reason to keep WinRAR installed :(

    I'm using the default dictioary size. However, I have enabled "Use large memory pages" and maybe it is helping the high speed as it is intended to do.
