    Recommendations for large-file ZIP program?

    Could anyone recommend a free ZIP program which will cope with <LI>command-line input (no GUI requirement, thank you very much!)<LI>creating large archives of at least 500 MB<LI>and at least 5000 files<LI>and which can make the resulting archive self-extracting.

    I have been amazed by the prices that PKWare want to charge for their self-extracting bit! And WinZip requires even more files for their command line tool than for their GUI functions!

    Try GZip.

    Sorry, I didn't realise that was so important.

    Re: Recommendations for large-file ZIP program?

    Correct me if I'm wrong, but I see no sign of self-extraction/SFX?

    But your URL also included a reference to UNZIP/ZIP, which does appear on first glance to include this feature!

    Yes, otherwise I would use WinZip - for which we have an intergalactic licence!

    AFAIK, Gzip is a different algorithm than Zip.

    John, I'm confused, I thought there was a Winzip Self-Extractor Personal that is built-in to the basic product?

    Check out the Archiver Comparison Test site http://compression.ca/act-win.html for a list of archivers and their features.

    I suppose with "self extraction" you don't necessarily need ZIP format?

    Hi John

    I don't know about the "command line" capabilities, but you might check out Ultimate Zip.
    It's got to be one of the best compression programs and it's <img src=/S/free.gif border=0 alt=free width=30 height=15> .

    Have a Great day!!!

    Terry - the compression time and size comparisons are quite fascinating for geek-orientated personages! What an unexpected variation in the results... Sadly he does not include "Command-line Interface" as one of the features of each archiver, which was one of my four Criteria!

    Re: Recommendations for large-file ZIP program?

    Performance depends on the algorithm used and implementation tricks.

    I did a similar analysis for QuickSort a few months ago.
    If I ever recover from the shock, I'll post the results, maybe even a demo of the test.
    Results were quite surprising.

    There is an indication (sort of)..
    If the table mentions DOS - it has to have a command line interface!

    Plus, there are links for any you want to read more about.

    I am deliberately avoiding giving a specific recommendation as I haven't used any of the "free" ones in anger - either command line or GUI.
